Abstract
Pick-resistant handcuffs having two fixed, arc-shaped hooks and one pivotable, arc-shaped hook. The two fixed ring hooks engage each other to form an accommodation chamber for receiving the pivoting hook penetrating into an open side of the accommodation chamber. Central channels are cut in the teeth outer periphery and accommodate a stop projecting part between the lateral edges of the teeth that inhibits unlocking the stop members of the ratchet attached to the two fixed hooks. Elastic members biased toward the teeth are disposed on either side of the stop projecting part act independently to provide ratchet stops to each tooth edge, and the stop projecting portion blocks insertion of a pick and unlock both of the two ratchets simultaneously.
