ABSTRACT:
A latch bolt assembly and a locking device for use in a latch mechanism which can be fitted to a door or the like. The latch bolt assembly includes a casing and a bolt device which is receivable within a guide passage in the casing for movement between latched and retracted positions. A biasing spring is disposed between co-operating stops on the casing and the bolt device so as to normally urge the bolt device towards the latched position. The locking device comprises a locking element movable between a lock position and a release position and a control member which controls movement of the locking element and an actuating member which causes movement of the control member.
