A coupling member has an internally threaded end portion and an opposite socket end portion with a pair of axially-spaced internal circumferential grooves. The internally threaded end portion receives an externally threaded end portion on a pipe, while the opposite socket end portion receives an end portion of another pipe that has an external circumferential groove aligned with one of the pair of internal grooves. A spline is inserted into the aligned grooves through a transverse hole in the wall of the opposite end portion of the coupling member to hold the coupling member and the other pipe against relative axial movement. The spline is a wire rope to provide high shear strength.
