The concept of a Shock Collar is simple: A character is forced to wear a SlaveCollar or torc and when he does something undesirable, as designated by whoever put the collar on him, he is shocked. Such things exist in real life for dogs, but it is more likely that the trope is in use as a way to replicate the iron slave collar with a SpeculativeFiction twist.

How it actually works is nearly always undefined. It's a metal ring, it hurts, end of statement. Sometimes it is electricity for some ElectricTorture, sometimes it's a generic AgonyBeam generated by some alien TechnoBabble. It makes a good RestrainingBolt for the plot, you can even spin some plot lines out of how to get it off (especially if it's designed to go off automatically if tampered with), and sometimes it'll have the added feature of being able to be pumped up to deadly levels so that it can also be, effectively, an ExplosiveLeash. On other occasions, expect some fun with Pavlovian conditioning.

!! Examples:

[[folder: Anime & Manga]]
* This happened in ''Manga/MahouSenseiNegima'' to the girls under slavery in the magical world.
* In ''Anime/{{Slayers}}'', captured Lina Inverse was restrained by a circlet that zapped her when she tried to use magic. They really haven't a slightest idea what [[AloofBigBrother her big sister]] used to [[GoodIsNotNice put her through]], however...
* Manga/InuYasha has a collar of enchanted prayer beads (or rosary) designed to make him hit the ground whenever Kagome says "Osuwari" or "Sit" / "Sit, boy". Kagome is an easily pissed off {{Tsundere}} Type B. Bad day for [=InuYasha=].
* {{Yaoi|genre}} series ''LightNovel/AiNoKusabi'''s plot revolves around how BadassBiker Riki was made into a SexSlave by [[BastardBoyfriend Iason Mink]]. Each "Pet" gets an identity ring in the standard form of jewelry like earrings, necklaces and such. Iason uniquely makes Riki's a cock ring which doubles as a RestrainingBolt Shock Collar whenever Riki rebels. Which is often.
* In the "Queen of the Adriatic Sea Arc" in ''LightNovel/ACertainMagicalIndex'', several of Biagio Busoni's enslaved nuns are [[GoGoEnslavement forced to wear enchanted clothing]] that causes them incredible pain if they try to escape or use magic. Sisters Lucia and Angeline manage to modify their clothes to power up their magic instead, but they still experience pain when they get out. Touma's [[AntiMagic Imagine Breaker]] is used to destroy them.
* The Caged Bird Seal of the Hyuga clan in ''Manga/{{Naruto}}'' works this way, in addition to sealing off the Byakugan after the wearer's death. With a single gesture, a main branch member can cause agonizing pain to a branch member who even ''seems'' to be acting out of line.
* In ''Anime/CaptainEarth'', Daichi, Teppei, and Hana are briefly forced to wear "lead gear", a headset-like device that causes them pain if they try to venture too far from the military base where they're quartered, or at the press of a switch. Daichi braves his way out of the perimeter, summons his Livlaster, and blows the broadcast antenna away.

[[folder: Comic Books]]
* The more villainous members of DC's Comicbook/SuicideSquad were fitted with these on missions. If they got ''too'' out of line, the collar could also be commanded to blow off their heads.
* 1980's British ''Comicbook/{{Starblazer}}''.
** The Slave Collar had variable pain settings to punish wearers who disobeyed their owner.
** Issue 157 "Warworld", The Valk put headbands on their prisoners that can inflict any level of pain on their victims, up to and including death.

* [[http://archiveofourown.org/works/659590/chapters/1202775 This fanfic]] shows [[Webcomic/{{Homestuck}} Eridan]] being put in a shock collar to stop him swearing. Unfortunately, said collar was made by Equius, and so it sets off at "darn". Eridan eventually resorts to "Goodness, you've cracked my skull!"
* ''Fanfic/BloodAndHonor'': Vette is fitted with one when she's turned over to the authorities on Korriban. Her jailer makes use of it when she gets mouthy, which is all the time, so she ends up in a fair amount of pain. Sanguis, on the other hand, though given the controller, never uses it or even threatens to. When they leave Korriban, the collar is removed.
* In ''Fanfic/StarWarsTheSithZero'' Louise is outfitted with one during her time as a Slave to the Sith Empire.

[[folder:Films -- Animated]]
* At the end of the film ''Film/{{Garfield}}'', the main character steals a shock collar from the dog catcher. The collar is later strapped onto the dog catcher and used by Garfield for some good old LaserGuidedKarma.
* Cartman has a V-chip implanted in his skull in ''WesternAnimation/SouthParkBiggerLongerAndUncut''. It sends out an electric jolt when he swears, in an effort to make him stop swearing. It, for the most part, doesn't work; towards the end of the movie, it even turns into a DeusExMachina when the chip shorts and Cartman gains [[ShockAndawe lightning powers]] as a result.
* [[WhatCouldHaveBeen An early draft]] of ''Disney/{{Zootopia}}'' was set in a society in which the predators had to wear collars that would administer an electric shock if they got too excited, which was supposedly necessary to keep them from eating the prey animals. The creators found this to be too dark, and ended up dropping it as part of a massive overhaul of the entire concept and plot.

[[folder:Films -- Live-Action]]
* In ''Film/{{Coneheads}}'', the two humans are carted off to the Conehead homeworld and kept in check by a collar with glowy red lights.
* The [[AwesomeMcCoolname eponymous hero]] wears one in ''Hell Comes to Frogtown''.
* In the 1996 version of ''Film/TheIslandOfDoctorMoreau'', all of the beast-folk have an implant that causes them excruciating pain when a remote control is triggered. This system of keeping them in check backfires when the Hyena-Swine figures this out and removes his own implant, then steals the control device to use it to dominate the others.
* In ''Film/CrankHighVoltage'', Chev Chelios encounters two assholes that are torturing a dog with a shock collar even though it was obeying their commands. Chev tells them off, takes the collar, and puts it on. He then makes them shock him to power up his artificial heart.
* ''Film/SavingSilverman'' used this as a form of aversion therapy - if Darren mentioned his late-girlfriend on a date, he'd get zapped by the stickers on his nipples.
* The prisoners in ''Film/BreathingRoom'' are all wearing Shock Collars which are rigged to deliver a deadly voltage if they try to leave the room.
* In ''[[Film/{{Garfield}} Garfield: The Movie]]'', [[BigBad Happy Chapman]] equips Odie with a shock collar.
-->'''Garfield:''' [[AndThatsTerrible That collar is inhumane!]]
* ''Film/VirtualCombat'': A CorruptCorporateExecutive whose company sells virtual reality sex programs discovers a way to download the virtual girls into artificial clone bodies. He also forces them to wear electric collars to better control them.
* ''Film/ThorRagnarok'': Slaves on Sakarr have small discs attached to their necks that deliver a powerful electric shock if they get out of line.

[[folder: Gamebooks]]
* ''Literature/CavernsOfTheSnowWitch'' has the [[BigBad Snow Witch]] fit collars onto her slaves, so that when they disobey her orders, they get choked.

* In Harry Harrison's ''[[Literature/TheStainlessSteelRat The Stainless Steel Rat's Revenge]]'' [[note]]and ''The Stainless Steel Rat Wants You,''[[/note]] the Grey Men attach one to James ("Slippery Jim") diGriz, connected by a cable to a control box. It inflicts searing pain by [[TechnoBabble stimulating neurons]] in the brain.
* The Literature/MichaelVey series introduces Dr. Hatch (leader of the Elgen company) who enslaves what he terms "the scum of society" (drug addicts, hardcore criminals, etc) by making them a tempting offer. Once they accept, a shock collar is placed around their necks and Hatch jolts them with electricity if they disobey.
* ''Literature/HanSolosRevenge'': The Lurrian slaves captured by Magg and Zlarb are chained together, the collars acting as Shock Collars: the slavers can hit the whole string at once in an emergency.
* Creator/JimButcher's ''Literature/CodexAlera'' has slave collars that will hurt the slave if they disobey or go against the master's will (to the extent that calling the person "bad" for no reason will hurt them) and send signals of pleasure when the person obeys. They often drive the victim completely insane, and it's played for every possible drop of horror.
* A similar device is used in ''Literature/ParableOfTheSower'' and its sequel, by slavers to keep their slaves in line. Lauren and her community also have these put on them when they are attacked and captured in the second book.
* Voluntary example: In the ''Literature/DreamPark'' series, Gamers wear remote-control amulets that deliver a mild electrical stimulus to inform them that they've been killed out of a scenario. The initial shock is merely uncomfortable, but if a player stubbornly refuses to lie down and "die" when the simulation demands it, the voltage can be increased to inflict actual pain. (Presumably they're required to sign a release to allow this.)
* in ''Literature/TheRedVixenAdventures'' when captured Rolas is given one that triggers if he goes through his cell's door (but not the vents) without the Red Vixen's permission, or if he gets more than five meters away from her when she takes him for a "walk." Ali is fitted with an ankle bracelet that does something similar when she's arrested.

[[folder: Live Action TV]]
* ''Series/BabylonFive''
** When the captain of Babylon Five, John Sheridan, found himself captured by the Earth government, who had recently given themselves a little ''[[Literature/NineteenEightyFour 1984]]'' ShoutOut by setting up the Ministry of Peace, he had a Shock Collar put in place as a RestrainingBolt to explain [[WhyDontYaJustShootHim why he didn't just attack]] the torturer who was trying to make him [[strike: [[Series/StarTrekTheNextGeneration see four lights]]]] sign a confession.
** A torturer/assassin makes G'Kar wear one. One of his political enemies on the Kah'Ree had just died, and wished to exact revenge.
* ''Series/StarTrekTheOriginalSeries'' had two episodes with collars that inflicted pain:
** "[[Recap/StarTrekS2E16TheGamestersOfTriskelion The Gamesters of Triskelion]]": Used by the title characters on their thralls.
** "[[Recap/StarTrekS3E1SpocksBrain Spock's Brain]]": Belts used by the Eymorg women on their male slaves and the captured Enterprise crew members.
* Both ''Series/TwinPeaks'' and ''Series/{{Cheers}}'' used the gag in which the wearer of the collar gets hold of its control box and uses it in the mistaken belief that it will shock the other person instead of himself.
* Chiana is wearing one of these when she first appears on ''Series/{{Farscape}}'', activated by a button on her handler's forehead. In another episode, the entire crew is fitted with collars- even Pilot.
* In an episode of ''Series/BuckRogersInTheTwentyFifthCentury'', Princess Ardala tells Buck that, when he marries her (due to her holding Earth hostage with an invincible KillSat), she will have him fitted with a lovely, decorative choke collar. If he displeases her, the collar will gradually constrict until he dies.
* In an episode of ''Series/MarriedWithChildren'', Al Bundy had to wear one.
* These collars are worn by the imprisoned women in the "Gladiatrix" episode of ''Series/BirdsOfPrey''. It also drugged them to the point of insanity.
* ''Series/TheOuterLimits1995'':
** The aliens in the episode "Rite Of Passage" put shock wristbands on the humans they were raising to prevent them from trying to leave their enclosure. It wasn't due to malice; the woods were full of dangerous creatures.
** "The Grell" from the episode of the same name are a race of RubberForeheadAliens who were enslaved by humans. They all wear shock collars that electrocute them if they disobey their masters.
* Human slaves in Pylea wear these on ''Series/{{Angel}}''.
* The beginning of the ''Series/{{Sliders}}'' episode "In Dino Veritas" is set in a world where all people wear shock collars that prevent them from lying.
* Creator/DavidCross has to wear one of these at the beginning of the second episode of ''Series/MrShow'', as part of a government program monitoring artists. He gets a constant electric shock if he stands on a stage.
* Lily gets the idea of Barney having to wear one (or rather, a cock shock ring) to get him to behave in ''Series/HowIMetYourMother.''
* ''Series/PersonOfInterest''.
** In Season 3 Root wears a device on her ankle implied to do this if she tries to break out of the Faraday cage Finch has her imprisoned in.
** In "4C", Reese is stuck on an airplane with the VictimOfTheWeek whom he finds rather annoying. Turns out he's wearing a shock belt, so Reese has a lot of fun with the remote [[PerpSweating until he gets the information he wants.]] Then Reese hands the remote to the stewardess, telling her that it's his beeper and that [[ComedicSociopathy she should 'alert' him if the POI gets out of his seat.]]
* In the mini-series ''Series/HouseOfFrankenstein1997'' a vampire tries to control the title character with one of these. The next thing the audience sees is Frankenstein's monster ripping off the collar after impaling said vampire.
-->"They were fools to think they could control ''me'' with electricity."
* The prison where Polaris and other mutants are held in TheGifted2017 uses shock collars to inhibit the mutants' ability to use their powers.
* In ''Series/KaizokuSentaiGokaiger'', Joe Gibken was forced to wear one that doubled as a tracker when he escaped from the Zangyack empire, but only activated if he tried to remove it. When he meets Captain Marvelous, after fighting alongside each other for a bit, Marvelous rips the collar out of him by ''sheer force'', freeing Joe of it.

[[folder: Newspaper Comics]]
* In one ''ComicStrip/{{Zits}}'' comic, Jeremy's mother forces him to wear a shock collar to stay at home after he breaks curfew one time too many.
* There was a series of ''ComicStrip/{{Dilbert}}'' strips where the employees all had to wear headbands that the boss could use to shock them at will. Dilbert reprogrammed his to redirect its signal to Wally.

[[folder: Video Games]]
* ''VideoGame/BaldursGate II'' has one trippy level where you follow a band of kidnapped actors into a PocketDimension where the slaves are kept in line by a magical version of these collars. If you're [[SchmuckBait schmuck enough to fall for the bait]], you can pick them up and try them on.
* In a case of Shock Collars being used for good, in ''VideoGame/BatmanArkhamAsylum'' the inmates have shock collars (dubbed "Suicide Collars") that double as life sign monitors. We see them demonstrated at the beginning as the only thing that can help keep Killer Croc under control in a ChekhovsGun moment.
** A bit more of a straight use of this trope occurs in the game as well, since SelfDemonstrating/TheJoker uses them to keep tabs on his goons (and as an alert system to where Batman is or has been) [[FridgeBrilliance and presumably also uses them when they get too out of line]]. Batman can also overload the collars with a specialized batarang so that they shock the goon wearing it into unconsciousness.
* ''VideoGame/DungeonSiege II'' had your character wearing one near the start, after being captured by dryads.
* In ''VideoGame/EnslavedOdysseyToTheWest'' a slavers' headband is the (initial) reason Monkey goes along with Trip in the plot; in the gameplay it also provides a reason to keep the player character close to Trip at times with the headband programmed to deliver painful shocks that eventually kill you if you wander too far from her.
* In contrast to the [[ExplosiveLeash exploding slave collars]] in ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'', ''VideoGame/{{Fallout 4}}'' (specifically, the ''Nuka-World'' DLC expansion) features shock collars, used by the Nuka-World raiders on the hapless traders and settlers they've enslaved. If you side with the raiders, one of the [[SideQuest radiant quests]] is to find randomly selected [=NPC=]s and place a shock collar on them. You can equip one yourself, but it doesn't do anything, considering that by the time you can get one, you've been designated the Overboss of the raider gangs.
* The ''VideoGame/KingdomOfLoathing'' [[WebGames Web Game]] has the Stab Bat, a familiar with the unfortunate habit of stabbing the player rather than the enemy every now and then. The familiar-specific equipment is, appropriately enough, a Shock Collar.
* In ''VideoGame/MOTHER3'', Salsa the monkey has a Shock Collar that is used by Fassad to punish him.
* In ''VideoGame/StarWarsTheOldRepublic'', slave girl Vette has one that the Sith Warrior can choose to abuse. However, you can also remove it for VideoGameCaringPotential.
* In ''VideoGame/WorldOfWarcraft'', Thok The Bloodthisty, a Devilsaur ([[CallARabbitASmeerp a T-rex]]) that's a boss in Siege of Orgrimmar, has a shock collar by the orcs that are trying to tame him as a beast of war. Unfortunately, the shock collar ends up causing damage ''to the players'' during the fight by zapping them with electricity.

* ''Webcomic/TheAdventuresOfGynoStar'': Supervillain Vlad Deferens tries to use a shock collar to make Gyno-Star compliant and obedient.

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', the [[WellIntentionedExtremist Grey Cult]] uses magical shock collars donated by the [[ReligionOfEvil Totenkopfs]] to force captured demons to work in the cult's army as foot soldiers against the cult's enemies...but once a spell ends up disabling the collars, the once enslaved demons lash out horribly and turn against their "masters". It later turns out that the Totenkopfs only used the cult for their own ends to help further test the collars' effectiveness. Once they make some adjustments, they force a few captured higher demons to wear the new, modified collars which will force the demons to work as their more or less loyal minions and use these new lackeys to infiltrate demon hordes so that the Totenkopfs can learn the demons' weaknesses.

-->'''Foxxy:''' Well I'll be a monkey's uncle.\\
'''Clara:''' Oh, so it's okay when ''you'' say it. ''(gets shocked)''
* In the ''[[WesternAnimation/TheFairlyOddParents Fairly Odd Parents]]'' episode "Wish Fixers", the [[CorruptCorporateExecutive Pixies]] make Timmy sign a contract that would supposedly help him get rid of any "bad" wishes and put collars on Cosmo and Wanda that release an electric shock every time they grant a wish that is considered "bad". In fact, the only good wish on the contract is handing Fairy World over to the Pixies. However, thanks to a loophole in the contract (making an irresponsible wish that is at the same time responsible will cause the contract to be null and void), Timmy wishes for both his godparents to be made of rubber, making them immune to the shocks and nullifying the contract as a result.
* In ''WesternAnimation/{{Futurama}}'s'' third movie, ''Bender's Game'', Leela gets a shock collar to condition her to give up violence and profanity and all that other fun stuff. She learns to associate the shocks with pleasure.
* Worn by Shego's subjects in her future dystopia in ''[[WesternAnimation/KimPossible Kim Possible: A Sitch in Time]]''.
