The door-lock has two handles (43, 46), a catch and a bolt (37). The latter is movable from the engaged into the free position by the handle (46) on one side only. The bolt can be arranged to lock the catch, which can be actuated by each handle independently. The ends of the components coupled to the handles and which actuate the catch can be arranged to fit together in a sandwich pattern. ADVANTAGE - Rapid opening in an emergency.
