The disclosed invention relates to a novel joint for joining pipes. More particularly, the joint employs offset, overlapping locking tabs on a male and a female joint member, which locking tabs are spaced to permit the locking tabs on the female joint member to slide past the locking tabs on the male joint member. The joint members are then rotated, overlapping the locking tabs to lock the joint axially. A locking pin and locking pin aperture are provided to lock the joint rotationally, when the locking tabs are aligned to overlap. The locking pin is rotatable, and has a chamfered portion whereby the female joint member can slide over the locking pin, then rotated to engage the locking pin. To disassemble the joint, the locking pin is rotated ninety degrees to orient the chamfered portion of the locking pin circumferentially, whereby the joint members may be rotated, again permitting the female joint member to slide over the locking pin. The joint is particularly suited to applications involving profiled pipes wherein internal profiles, such as longitudinal grooves, of separate pipes must be aligned.
