The joint comprises a flared end (3) on one pipe (4) and a plain end (1) on the other (2). The plain end has an annular ridge (6), and it is held in place inside the flared end by a split metal locking ring (7). The locking ring has notches in at least one of its faces which allow it to be compressed for insertion into a cavity (10) in the flared end, to expand as it passes over the ridge (6) and then contract again to lock the plain pipe end in place, A second cavity (13) inside the flared pipe end holds a seal (5). |
