The spigot end of one pipeline element is inserted in the socket end of the other pipeline element and is sealed by a gasket. To the end face of the socket end is connected a thrust preventing ring, which is secured by claws to part of a collar. A retaining ring engages on the inner surface of the thrust preventing ring and its inner face is provided with a tooth system, which is fixed to the surface of the spigot end. Between the end face of the socket end and the retaining ring is provided a thrust ring, which exerts a pressure on the retaining ring. By means of in each case one packing element on the side of the thrust preventing ring facing and remote from the socket end, said ring is located in a sealed and consequently corrosion-proof zone. Thus, the socket joint is secured without any modification to the pipeline elements. |
