<p>This device for fixing a rail (7 or 8) onto a vertical support stiffener (3) is characterised in that it has a tubular structure, capable of receiving, in a horizontal through-passage defined by openings (12, 13) made facing each other in its opposite walls, a clamp (9) whose ends (14, 15) are mutually symmetrical with respect to the mid-plane (16) of the stiffener, these ends receiving, in an open groove (19, 20), a plane flat piece (18) forming part of the rail (7, 8) to be immobilised, the clamp including a central bore (24) into which is engaged a screw (25) accessible from the rear of the stiffener, in such a way that rotation of the screw bearing on the inner wall of the stiffener exerts, by reaction, a movement of the clamp along the axis of this screw, thereby providing a clamping effect of the clamp and consequently the locking of the rail carried by the latter with respect to the stiffener. <IMAGE></p> |
