A flexible coupling member is constructed from a length of elastomeric cylindrical tubing. The opposite ends of the tubing are closed by axially spaced ribs positioned at right angles, and the outer surfaces of the flexible coupling between the ribs are bounded by smooth warped surfaces. The interior of the coupling may be hollow or solid. If hollow, a check valve may be provided in one of the end ribs or on one of the smooth warped surfaces, to control internal pressure.
