A coupling and anchoring system for coupling lengths of pipe and anchoring the lengths of pipe to a structure comprise a pipe coupling having an external peripheral groove defined by axially facing axial clamp engaging surfaces, said groove receiving an anchoring clamp. The anchoring clamp has corresponding axial coupling engaging surfaces for engaging the axial clamp engaging surfaces of the pipe coupling to restrict axial movement of the pipe coupling when the anchoring clamp is fastened to the structure. The anchoring clamp is formed from arced bands having laterally extending connecting portions and laterally extending arced elements. The laterally extending connecting surfaces and arcs combine to form dual fastener openings for optionally receiving fastening elements perpendicular and parallel to the longitudinal axis of the pipe coupling for optionally anchoring the system to perpendicular and parallel portions of the structure. The internal arc radius of the arced bands is comparable to the outer diameter of the external peripheral groove with the laterally extending connecting portions radially remote from the groove so that connection of the laterally extending portions prevents over tightening of the clamp. The coupling has an hour-glass cross section with the peripheral groove located axially interposed between the pipe stops and the clamp engaging surfaces such that the pipe lengths would not be axially coincident with the external groove.
