The center stop (8) is provided and designed for a dense front-side mutual impact contact of the hollow sections (2) at the connection point (9). It is located at the axial center of the support base (12). Figures 1 and 2 illustrate this training and

Arrangement.

The aforementioned offset fixed stops are located with their stop surface in each case in the immediate vicinity of the connection point (9). The first plugged hollow profile (2) slides over the this side of the connection point (9) located fixed stop along the rising

Wedge flank, where it is possibly deformed and aligned. It then beats on the other side of the

Clamp (9) located fixed stop. The second hollow profile (2) strikes after passing over its world-side fixed stop on the front side of the first hollow profile (2).

The sealing stop function of the center stop (8) can also be achieved with a different stop construction. Furthermore, it is possible to materially firmly and tightly connect the butted profile ends, for example, by a weld. On the base plate (10) on each leg (6,7) each have an axial rib (19) is preferably central
