Each of the profiles (1, 2) is provided with a rigid outer cast or forged outer end (8, 9) welded, glued or soldered to the edge of the profile (7, 10). Both ends (8, 9) are positioned beside each other and can be joined with a shear bolt (19) inserted into bores (32) leading through both of the ends (8, 9). Two pins (20, 21) are guided into transversally positioned bores at the shaft of the bolt (19), securing the arrangement.
