A self-locking joint particularly for shelf, rack and furniture systems, consisting of a vertical element (1) with recess (2) of the vertical element (1), and a horizontal element (11). The thickness of the horizontal element (11) corresponds to the recess (2) of the vertical element (1). The horizontal element (1 ) has a recess (6) of the horizontal element (11), wherein in the recess (6) of the horizontal element (11) on the front side of the horizontal element (11) there is, attached by a fastening element (8), a flexible fitting (7), having wings (7a) which form an acute angle with a horizontal level. The square endings (12) of the wings (7a) exceed the thickness of the horizontal element (11); or of a vertical element (1) and a horizontal element (11), alternatively of vertical elements (1) and horizontal elements (11) mutually comprising a recess (20) for positioning the coupler (21), corresponding to the recess (20), wherein on one or both front sides of the coupler (21) there is attached one or more flexible fittings (7), having wings (7a) which form an acute angle with the horizontal level, and wherein the square endings (12) of wings (7a) exceed the thickness of the coupler (21). Preferably, the vertical element (1) has a recess (3) for the fastening element (8), wherein the fastening element (8) exceeds the flexible fitting (7), where the height difference of the fastening element (8) corresponds to the recess (3) for the fastening element (8) at the front edge of the recess (2) of the vertical element (1). |
