ABSTRACT:
A coupling for a corrugated conduit has a body with a rotatable retaining ring. The ring has inwardly-projecting locking bars with two finger grips which project outwardly through slots in the body. When the finger grips are held and the ring is rotated, the locking bars are displaced inwardly to lie between adjacent corrugations of the conduit and retain it in the coupling.
