Abstract
The subject matter of this present invention is a pipe joint with a socket (1) and a pipe (2), that is closed by pushing a ring (3) onto the socket (1). The joint further comprises a sealing element (4) that is placed into a chamber (5) of the socket (1). The chamber is executed as a diametral expansion of the socket (1) and is deformed in a defined manner when the ring (3) is pushed on. Due to this the sealing element (4) between the wall of the chamber (5) and the pipe (2) is compressed. Furthermore, when the joint is closed, the socket (1) is compressed with the pipe (2), due to which a mechanically stable joint is produced, that additionally serves as an emergency seal.
