A bell and plain end pipe joint are provided wherein the plain end has a raised portion on its outside diameter. A series of locking segments fit into a circumferential groove in the bell of one pipe and engage both the raised portion on the plain pipe and a portion of the bell. Upon an increase in fluid pressure in the pipes, the pipes tend to separate axially and the locking segments also contact and bear against a different portion of the bell. The joint provides a novel means of distributing the axial thrust tending to separate the pipe being joined.
