Abstract: A dual-hook locking assembly mounted in a casing subassembly is actuated from outside of the latter by a handle which causes a locking subassembly to operate between an unlocked and a locked position. By rotating the driving handle, a gearing subassembly including a pair of meshed segmental gears drives the locking subassembly between the aforementioned positions. The gearing subassembly and the locking subassembly are directly interconnected. An adjusting subassembly is used for positioning the locking subassembly with respect to a strike plate of a door. The adjusting subassembly comprises several guiding plates. The latter and the gearing subassembly have a common center of rotation.
