Abstract

A retainer for retaining a corrugated conduit in a wall opening comprising a pair of rings provided by formation of a spring wire or a slit annular part wherein the retainer is insertable into the end of the conduit and is contracted with contraction of the conduit by an externally applied force to permit insertion of the conduit in the opening and then on release of the contracting force the retainer expands and holds two of the conduit corrugations outward of the opening on opposite sides of the wall to prevent pull-out or push-in of the conduit while also retaining an intermediately located corrugation of the conduit in sealing contact with the surface of the opening.
