ABSTRACT:
A pipe connector which comprises a tubular box member that is telescopically engageable with a tubular pin member, the members having corresponding frusto-conical inner and outer peripheral surfaces which overlie one another when the members are fully engaged together. To axially lock the members together, the frusto-conical surfaces are provided with pairs of interengageable annular projections and grooves. The projections and grooves have varying axial extents and spacings so that, as the members are telescoped together, in all intermediate positions of the members, there is sufficient contact between crests of the grooves and surfaces between the projections to prevent inadvertent premature engagement of a projection with a groove.
