The fastening, especially for temporary signs on a road or motorway safety barrier, has two jaws (1, 2) to grip the barrier (M), one of which has a system of levers (5, 6) to lock or release it. The lockable jaw has fittings for fastening it to a concrete or metal safety barrier, the latter using an articulated arm (8) which is retracted for use with a concrete barrier and deployed to engage with a metal one by means of a thrust heel (8a). The two jaws are attached to a cross-member (3) which has a notch (3b) for the top of a metal barrier. |
