ABSTRACT:
Disclosed is a handcuff having a pair of cheeks and jaw pivotally secured one to the other and movable between handcuff open and closed positions. The cheeks carry a lock assembly including a pivotally mounted bolt for locking the jaw and cheeks one to the other in the handcuff closed position and a leaf spring for biasing the bolt for movement into its locking position, the spring carrying a detent. The spring is slidable between a first position with the detent offset from the bolt to enable the bolt to move against the bias of the spring to unlock the jaw and a second position locating the detent in registry with the bolt to maintain the bolt in its locked position thus double locking the handcuff. A keyhole is provided through one of the cheeks and receives a bushing. The bushing terminates short of the other cheek and is disposed about a pin secured to the other cheek. Thus bolt head includes a shoulder located between the end of the bushing and the one cheek. The remaining part of the bolthead end between the bushing end and the other cheek is recessed or set back from the shoulder. Thus, direct access to the shoulder through the keyhole opening is prevented.
