<p>In a joint (1) composed of a joining component (2) and four panels (3, 4, 5, 6) in parallel and coplanar pairs, in which the joining component contains a cavity (2c) whose shape is complementary to and houses two shaped projections (32, 42) present on the edges of two (3, 4) of the said panels, the said joining component being connected at its back (2d) to the edges of the other two mutually neighbouring panels (5, 6), the said joining component (2) is made of synthetic resin, has a cross-section of defined width (W) and has on its back (2d) two recesses (7, 8) perpendicular to itself and complementary in shape to two peduncles (5p, 6p) that are formed on at least a portion of the length of the neighbouring edges of the said other two panels (5, 6) and can be pushed elastically into the said recesses (5p, 6p) in which they are reversibly retained. <IMAGE></p> |
