An adjustable pipe coupling assembly (10) has a first clamp (30), a second clamp (32), and means (38, 40, 44) for rotating the clamps independently about a first common axis shared by the clamps and extending vertically. The first clamp (30) includes a first pair of opposed ears (52, 54) spaced apart so as to allow a first pipe (16) to be located therebetween. Each one of the opposed ears (52, 54) has a hole (56, 58) formed therethrough. The pair of holes (56, 58) share a second common axis extending in a first horizontal plane and are adapted to receive first pivot means, such as a bolt (60), therethrough for engaging the first pipe (16). The first pipe (16) is, as a result, pivotable in a first vertical plane about the second common axis. The second clamp (32) includes a second pair of opposed ears (52, 54) spaced apart so as to allow a second pipe (18) to be located therebetween. Each one of the opposed ears has a hole (56, 58) formed therethrough. The pair of holes share a third common axis perpendicular to the second common axis and extending in a second horizontal plane, the pair of holes being adapted to receive second pivot means, such as a bolt (60), therethrough for engaging the second pipe (18). The second pipe (18) is, as a result, pivotable in a second vertical plane about the third common axis. The arrangement is such that, in use, the rotating means rotate the clamps so as to adjust the horizontal angle between the second and third common axes, and each of the first and second pivot means pivot their respective pipe so as to adjust the vertical angle between the first and second pipes.
