ABSTRACT:
A lock includes a lock housing (3), a bolt (20) which is moveable in the lock housing between an inwardly withdrawn and an outwardly extended position and which includes a weakened region (36). The lock also includes a blocking element (5) fixedly arranged in the lock housing, an interlocking device (12, 14, 16), and a bolt-carried abutment element (34) which is adapted to coact with the interlocking device (16). When the bolt is subjected to an outer force that exceeds a generally predetermined force, the bolt will deform in the weakened region (36) so that movement of the bolt between the outwardly extended and inwardly withdrawn positions will be blocked by the fixedly mounted blocking element (5).
