Stasis cuffs

Stasis cuffs are devices in the Transformers Animated continuity family.

Stasis cuffs are Transformer-sized handcuffs with a rigid block between the individual cuffs. They place the Transformer they are used on into a form of stasis lock, which leaves the victim fully conscious and capable of speech, but - once active - unable to move in any other way or use any special powers they may possess.

When Optimus Prime refused to agree to cover up recent events with Megatron and the AllSpark, Sentinel Prime arrested him, and threatened to use a pair of stasis cuffs on him. When he later tried to use them on Optimus, however, he quickly found them on his own wrists. Optimus would get the chance to use the same pair on Starscream later the same day.
