They are provided with a union working in conjunction with a countersunk hole in which they are held with clearance. The bolts are threaded on their section extending out of the plate (20) on the door panel side. The door post (2) involved has a profiled plate covering (3) with an L-shaped cross-section, one arm (8) of which has a narrow groove (22) in which a further L-shaped covering part (23) can be inserted to cover the fixture screws (24) which secure the main profiled plate to the door post.
