An anti-rotational pipe coupling system is disclosed having pipe segments with end surfaces in which receptacles are arranged at spaced intervals circumferentially around each pipe. Interference bodies in the form of elongated pins are received within the receptacles of one pipe segment and extend outwardly from the end surface to engage complementary receptacles in another pipe segment arranged in facing engagement. The pins bear against the pipe segment sidewalls within the receptacles to prevent relative rotation of the pipe segments about a longitudinal axis coaxial with them. The pipe segments are received within a tube which uses flexible splines engaging concentrically aligned grooves in the tube and the pipe segments to prevent relative axial movement between the segments.
