Abstract: A pipe and pipe coupling assembly (10) including a pipe (20) having a first end (72) and a pipe (22) having a second end (74). The first end (72) includes a threaded portion (60) and a keyway (32), and is adapted to slidably engage the second end (74). The second end (74) includes a key portion (36) that is adapted to engage the keyway (32), thereby impeding the rotation of the pipe (20) relative to the pipe (22). The pipe and pipe coupling assembly (10) further includes a coupling member (34) adaptable to be rotatably attached to the second end (74). The coupling member (34) further includes a threaded portion (58) operable to engage the threaded portion (60) of the first end (72), thereby removably coupling the pipe (20) to the pipe (22) in a keyed, end to end relationship.

Abstract: A joint for joining pipes, wherein 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 to lock the joint axially. A locking pin and locking pin aperture lock the joint rotationally, when the locking tabs are aligned. The locking pin is rotatable, and has a chamfered portion whereby the female joint member can slide over the locking pin to engage the locking pin. To disassemble the joint, the locking pin is rotated ninety degrees to orient the chamfered portion circumferentially, whereby the joint members may be rotated, permitting the female joint member to slide over the locking pin.
