Roadblocks for improved road safety barriers, of the type that are constituted by a dihedral. Straight of equal faces in the form of triangles with rounded free vertices, the means of connection to the barrier being a crossbeam with its ends recessed, which is essentially characterized in that the internal faces of the dihedral are welded to the recessed ends of the crosspiece, which presents centrally and internally a frame joined by welding on the contour of the anchor drill, with two peripheral fins capable of being folded back over the aforementioned central hole, for the purpose of attaching to the head of the anchor rod.
