For braces, railings (10) and similar components of scaffolding, support structures and similar tube constructions the tube component has a hook (13) at least at one of its ends (11,12) for its fixture to another structural part. The tube end is lined with a socket, the outer contour of which is approximately equal to the inner contour of the tube end. The length of the socket surpasses that of the hook. The socket is so formed that out of a holding rib (16) a hook loop (17) is created. The free face side of the tube end and the outer face side of the tube socket are flush with one another. |
