<p>The system secures a fitting to a profiled section, the fitting having a lug passing through a wall of the section. An opening is formed in the section wall, of shape corresponding to that of the lug (15), which is then inserted in the opening. A recess formed in the lug is engaged by a stop preventing it being pulled out again. The lug is pressed into engagement with the stop by a wedge-piece acting between the profiled section and the lug.</p> |
