<p>The joint comprises an angle bracket (30) one of the wings of which is cut in order to produce two segments (31, 31a) of the same dimensions which are separated by a free space (32), while each segment has a clip-shaped profile (33, 33a), the second wing being cut into four identical tongues (34, 34a, 34b, 34c) which are each corrugated so as to constitute a dish-shaped passage (36, 36a, 36b, 36c), the tongues being separated from one another by free spaces (35, 35a, 35b) so that the free space (32) is opposite the free space (35). <IMAGE></p> |
