Abstract
A safety shield for double-lock handcuffs having a first lock for disengaging or releasing the wristlets after the same have been applied to the wrists of a prisoner, and a second lock for fixing the preset contracted position of the wristlets on the prisoner's wrists. The box-like shield comprises access slots in a wall thereof through which a portion of the associated handcuff key may be inserted to actuate the second lock without opening the shield or revealing the first lock or removing the shield from the handcuffs. This arrangement permits the shield to be secured over the handcuffs prior to application to a prisoner and thereby enhances the officer's safety.
