A coupling for connecting pipe ends includes a sleeve member having radial flanges at the longitudinal ends thereof, a plurality of spaced ribs, tightening straps disposed about the sleeve between the spaced ribs, and a resilient collar extending into the sleeve for receiving the pipe ends, the resilient collar also extending around the longitudinal ends of the sleeve member and around the radial flanges, the resilient collar further having a ring-like section extending on the longitudinally inner sides of the radial flanges such that the ring-like section grips onto the longitudinal inner sides of the radial flanges.
