Each crash box comprises a left member (20) and a right member (21) formed of sheet metal, which are jointed together and have top portions (24,25) overlapping each other and bottom portions (22,23) overlapping each other to form double-sheet tabs (34,35). These tabs extend out over the top and bottom surfaces of the bumper beam and are fastened to these surfaces.
