Pins of the fastening element fit into holes provided at regular intervals on the center lines of concave edge portions of the panel. The angled edge of a locking cap slipped over the body of the fastening element and fixed to it by a screw locks the element to the edge portions. The locking cap may be dispensed with by using a screw, driven through a hole in the base plate of the panel, to secure the body of the fastening element to the panel. The fastening element and the panel ensure good stability and an attractive appearance.
