A lock device comprising a lock housing (10, 20), a bolt element (30) mounted in said housing, and a lock cylinder (40) which is mounted on the outside of the housing and which includes a cylinder house (41) and a cylinder plug (42) which is mounted for rotation in an opening (41a) in the cylinder house. The device further includes in the lock housing a non-circular mounting hole (22) which is adapted to receive an anchoring part (42c) at the inner end of the cylinder plug. This anchoring part has a cross-sectional shape that permits insertion of said part into the mounting hole. A fixating means (23) on the lock housing co-acts with means (41c) on the lock cylinder for blocking movement of the lock cylinder in a radial direction while permitting the cylinder to move in an axial direction. In a cylinder plug mounting position, when the anchoring part is aligned with the mounting hole, the lock cylinder is allowed to move in an axial direction. Axial movement of the lock cylinder is prevented in a cylinder plug fixated position when the anchoring part is in engagement with the lock housing. This enables a lock cylinder to be fitted to and dismantled from a lock housing in a simple and inexpensive fashion. |
