Abstract (en)
The present invention relates to a self-locking coupling particularly for profiled elements of casements, door- and window-frames and the like, which has the peculiarity of comprising a coupling tang (2) which extends from an abutment body (3) and ends with coupling protuberances (10). The coupling protuberances (10) have a smaller width and a greater length than the distance defined between the opposite wings (11) which delimit the coupling seat (12) defined on a profiled element (13). The coupling protuberances (10), on the face directed towards said abutment body (3), define opposite inclined planes (20) engageable with the wings (11) to generate a movement of said coupling (1) in the direction defined by the tang (2) upon the rotation of the coupling (1) about said direction. The wings (11), with the coupling (1) applied to the profiled element (13), are clamped between the coupling protuberances (10) and the abutment body (3).
