Abstract
A lock having a hand-slideable lock-bolt. A lock body has a transverse bore passing therethrough and in which the lock-bolt can be mounted. The lock-bolt is movable between locking and unlocked positions. A retention element located in the lock body but externally operable prevents the lock-bolt when in the unlocked position from being removed from the lock body. By externally manipulating the retention element the lock-bolt can be released for complete removal from the lock body. A key operable lock cylinder is located in the lock body and prevents the retention element from being manipulated to release the lock-bolt for removal unless a key is inserted in the lock cylinder and the lock cylinder is in an unlocked position.
