Abstract
A lock for a swinging door comprises a lock casing having a fore-end and at least a first side wall. A first bolt is spring-loaded for engagement with a stationary engagement member of a door case or the like and is movable between a locking position in which it does not extend beyond the fore-end, and an open position, in which it is retracted into the lock casing. The lock casing has an opening in its fore-end and its first side wall, said opening enabling engagement between the stationary engagement member and the first bolt in its locking position.
