The edge of the door opposite to that one which has the hinges thereon enters a second cavity in the fixed works (wall) opposite the first cavity during closing. A lock is installed in the main body of the door, this lock also entering the second cavity, only its keyhole or control member being accessible from the inside or outside, the accessibility being effected via slits in the fixed works (wall).
