The block is made of an elastic material, preferably vulcanized rubber and especially recycled rubber, and has reflective means on at least one of the lateral faces especially a cat's-eye or a reflective foil. The block exhibits recesses in the form of passholes for screws, which allow a point by point fixation of said block.
