Abstract
A pipe joint is locked against separation by a split snap-ring assembly including a ring adjustor outside of the plane of the snap-ring. The snap-ring assembly is especially well suited for use with spigot and socket joints of large diameter pipe. The pipe joint may use an annular gland or collar piece such that relative rotation between the spigot and socket may be allowed thereby minimizing stress.
