A security door mounting arrangement for a safe (10) including a substantially rectangular-shaped block for the body (20), having a base (22), a rear wall (in the direction (23), a pair of side walls (24) and a top (25), all defining the cavity (21), and an opening (in the direction (26)) defined by a door jamb (27). A hinged door (40) includes a locking assembly (60), including a crank assembly (62). The crank assembly (62) includes a central crank (63) comprising a disc plate substantially parallel-planar with a main panel of the door (40). The crank (63) is operable by a handle installed on the front face of the door (40). The handle and the central crank are rotatable together coaxially and about a common axis A.

A hinge to open or to close a door, for example a door of an electrical cabinet of an aircraft, including at least one first wall and one second wall defining an angular opening of the hinge and a hollow internal space of the hinge sized to receive a cable. The first wall and the second wall are positioned relative to one another in order to open the hinge in a cable insertion or extraction position to allow the cable to pass through the angular opening of the hinge inside or outside the internal space, and to close the hinge in working positions of the hinge between a maximum open position of the door and a closed position of the door to block the angular opening of the hinge so as to be able to enclose the cable in the hollow space.
