摘要

The device comprises a flexible ductile sealing element (5), which is positioned inside hollow portions (1,2), such that a volume (18) inside the hollow portions that can be welded are separated by a welding area. A center body (4) is provided, which is connected with the sealing element. The sealing element is formed in the form of a hose-like hollow profile (13).
