Abstract
Said improvements consist in substituting the two threaded housings made in the concrete seat for direct and selective reception of a screw with a second screw of expanded head, in such a manner that two identical screws 8-8' are contained in one and the same box 1', of greater length, in which two operating positions are established for each one of said screws, by means of pairs of grooves 16-16' and 17-17' of the upper wall of the box, into which grooves are selectively locked transverse ribs 15 of the plates 12-12' which participate in the fastening of the rail 11. In this way, the change manoeuvre is much more rapid as there is no need totally to unscrew the screw and to screw it up again, it sufficing to loosen the nuts 9-9', move the entire assembly sideways and retighten them.
