A locking system for safe doors of the type comprising a turnable handle or handwheel for operating one or more sets of bolts between a locked position, wherein the bolts project into the door rim, and an unlocked position, wherein the bolts are withdrawn from the door rim. The system is characterized by bolt-securing means in the form of locking pins adapted to be inserted, in the locked position of the bolt, into aligned bores formed through each bolt and through a wall of a fixed bolt housing block slidingly supporting the bolt during the displacement thereof between the locked and unlocked positions. The pins are displaced into their locking or inserted position immediately after the locking of the bolts during a continuous rotation of the handle. |
