Bodies having hollow sections and made of thermoplastic are tightly connected in the front to a molded body of a thermoplastic weldable thereto. The front end piece of each hollow sectioned body is introduced into a corresponding open recess molded in the molded body and having inside dimensions matching the front section of the hollow sectioned body so that the end piece of the hollow sectioned body rests against the wall of the recess. The front side and the edge are then welded to one another on their entire periphery, preferably by sinking into a groove of a welding tool shaped to correspond to the common edge. |
