<p>The fastener can be used for blocking a stack of adjacent modules threaded onto a receiving rail having a U section possessing arms with inner flanges. The fastener comprises a body (18) having a solid part provided with flexible frictional means intended to bear on the outer face of the flanges (14), and at least one pair of elastic tabs (22) having a locking shoulder intended to be applied against the inner face of the flanges, and a clip (20) which can be displaced relative to the body (18) in the longitudinal direction of the tabs (22) between an upper position towards which it is pushed by a return spring and in which it frees the tabs, and a lower position in which it snaps elastically onto the tabs (22), in which the clip (20) holds the tabs sufficiently bent towards the inside for the shoulders to be able to pass between the flanges (14). <IMAGE></p> |
