摘要： A pipe connection is formed between a relatively soft pipe segment and a stiffer socket by inserting a split securing ring in a groove of the socket, then spreading this ring and inserting the pipe segment through the split ring into the pipe segment without contact with the split ring. The mounting body maintaining the spread state of the split ring is then removed to allow the spring ring to engage with its intrinsic elastic force along the periphery of the pipe segment. Even if the inner surface of the split ring is provided with a corundum layer or like friction-enhancing structure there will be no damage to the outer periphery of the pipe which might interfere with sealing.
