ABSTRACT:
A connector fitting for a corrugated conduit comprises complementary first and second parts together defining a cylindrical body. They are molded in one piece with a strip which links the first and second parts together in the manner of a hinge. There is at least one rib on each part disposed in a plane perpendicular to the longitudinal axis of the part. At the free end of the first part opposite that adjoining the hinge is a first locking member. There is a complementary second locking member at the free end of the second part opposite that adjoining the hinge. A third locking member is provided on one edge of the first part adjoining the hinge and a complementary fourth locking member on an edge of the second part adjoining the hinge. The first locking member comprises a first bar and an outwardly facing first hook at the end of the first bar. The third locking member comprises a second bar and an outwardly facing second hook at the end of the second bar. The second part comprises two openings in corresponding edges adapted to receive the first and second bars and having flats at their outer edges adapted to cooperate with the first and second hooks.
