A fastening device for a door permits the actuation thereof by a handle, a locking element, or a key of normal kind. A bearing, fast to the wall of the door, can receive either a standard shaft, or a lock cylinder, or again a shaft having a head of particular shape, each of these three members being associated with a same operating handle and a same bolt.
