COUPLING FOR CORRUGATED TUBING ABSTRACT OF THE DISCLOSURE A molded plastic fitting for joining the ends of corrugated non-metallic conduit includes a chamber having an open end for receiving the end of the conduit with locking tabs joined to the peripheral wall of the chamber and extending into the chamber in a direction axially away from the open end. The tabs terminate in a distal end arranged to latch between adjacent corrugations on the end of the conduit to maintain the conduit in the chamber. The peripheral side wall of the chamber is circumferentially continuous and of generally uniform thickness about the open end with a first pair of diametrically opposed sections of the side wall being spaced and configured to closely engage and guide the exterior of the conduit during its entry into the chamber. A second pair of diametrically opposed sections of the side wall are integrally joined to the first pair circumferentially intermediate thereof by smooth transition wall sections. The second pair are spaced and configured to lie radially outward of the conduit a substantial distance. The locking tabs have their base portions integral with and carried by the second pair of wall sections with an elongated body of each locking tab being relatively rigid but having a thin flexible pivot section at the base portion.
