Abstract
A safety shield for double-lock leg cuffs having a first lock for disengaging or releasing the leglets after the same have been applied to the legs of a prisoner, and a second lock for fixing the preset contracted position of the leglets on the prisoner's legs. The box-like shield comprises access slots in a wall thereof through which a portion of the associated leg cuff key may be inserted to actuate the second lock without opening the shield or revealing the first lock or removing the shield from the leg cuffs. This arrangement permits the shields to be secured over the leg cuffs prior to application to a prisoner and thereby enhances the officer's safety. The safety shield is also suitable for use with handcuffs including a pair of wristlets pivotally and rotatably connected by either an enlarged ring portion or a short link chain.
