Abstract (en)

[origin: WO9924752A1] A pipe joint consists of a socket and a spigot end introduced therein, a sealing ring positioned between the inner surface of the socket and the outer surface of the spigot end for sealing the space between said surfaces, and a locking device (10, 22) for preventing withdrawal of the spigot end from the socket. The locking device comprises one or several locking elements (22) positioned between the inner surface of the socket and the outer surface of the spigot end. The locking elements are adapted to prevent withdrawal of the spigot end from the socket by engaging the outer surface of the spigot end. The locking elements are at their surfaces adapted to engage the outer surface of the spigot end provided with engagement projections and/or the outer surface of the spigoto end is provided with engagement projections adapted to engage the locking elements. The engagement projections constitute a thread which makes it possible to separate the spigot end from the socket by screwing out the spigot end therefrom.
