There is fixed, on a wall, a section member having a substantially U-shaped portion provided with an upper leg extended by a lug formed with a window adapted for setting in position an appropriate retaining member in a position chosen on the wall. A vertical central zone of the U-shaped portion is provided with an opening through which passes a rotatable retaining member having an inner screw thread and a front portion provided with a thinned-out zone adapted for retaining a nut. A threaded rod is screwed into the retaining member and terminates into a flattened portion through which extends a vertical channel adapted for receiving a pin that maintains by penetration a lower lining panel board and an upper lining panel board. A counter nut is provided to lock the threaded rod on the retaining member.
