Combination lock for doors. It consists of a shaft (3) with two swivel buttons (4), manually actionable and situated on both sides of the door (1) and related to the corresponding trigger that locks a conventional lock. A vástago (9) blocks the trigger and allows the use of the lock (8) without the combination device. The lock (8) can be blocked by such trigger with two different combinations, from the internal face and the external face of the door. (Machine-translation by Google Translate, not legally binding)
