<p>A connector for flexible conduit of the type which is spirally wound to provide continuous, alternating, helically contoured ribs and grooves thereon. The connector, which is formed from spring sheet metal, includes an apertured socket having a dome-shaped web defining at its edge a single helix thread form adjacent the aperture in the socket. The helical edge of the web traverses a path corresponding to that of the helical grooves on the conduit whereby the conduit may be turned into the socket with the edge of the web advancing in the grooves and over the ribs in the manner of a nut thread on a bolt. A fitting joined to the socket carries an apertured disc spaced from the socket which the leading edge of the conduit threaded through the socket ultimately engages to limit the length of the conduit which may be threaded into the connector. The fitting also carries snap acting legs adapted to secure the connector to an apertured support member, e.g., a junction box or an adapter connected to the junction box, when the fitting is inserted into the aperture in said support member. Additionally, the socket element carries a locking tab which both bitingly and tensionally engages the conduit to inhibit reverse rotation of same in a direction which would tend to disconnect the conduit from the connector.</p> |
