Abstract: An axial force resisting pipe coupling for coupling pipes in aligned end-to-end relation. The coupling is of a simplified, economical construction comprising a plurality of axially aligned spaced clamps, including a central clamp and two outrigger clamps, attached to a common bar, and the coupling may be formed by retrofitting an existing central clamp with the outrigger clamps and bar. Each of the clamps consist of a generally circular band terminating in opposed connecting end flanges and are attached to the bar at the flanges by fasteners which also facilitate circumferential contraction and expansion of the clamps. Projections may be formed on the bands for embedding into the pipe members to minimize the likelihood of the pipes pulling apart due to high tension forces.
