A one-piece, flexible conduit connector for connecting an electrical conduit having a helically grooved outer metal sheath to an electrical junction box, the connector being generally cylindrical to conform roughly with the sheath of the conduit and having a central opening through which insulated wires extend from said conduit, an anti-short flange being formed by hemming the central opening, inwardly projecting barbs being formed on the walls of the connector to engage the conduit and the outer diameter of the connector being of appropriate size for insertion into the junction box wall opening.

1. A one-piece, flexible conduit connector for connecting an electrical conduit having a helical groove in an outer metal sheath and electrical wires within said sheath, to an electrical junction box having an opening formed in a wall thereof, said connector including:a circular face portion having a round opening formed therethrough; an anti-short ring surrounding said opening and projecting outwardly from a front surface of said face portion, said front surface of said face portion facing into said junction box; a pair of tongue members depending from opposite sides of said face portion, a pair of flexible walls depending from said opposite sides of said face portion between said tongue members, said flexible walls being opposite to each other around the circumference of said face portion and arcuately shaped to conform to said electrical conduit; a plurality of barbs formed on said flexible walls and positioned to engage said helical groove over a plurality of turns of said helical groove when said electrical conduit is screwed into said connector, said barbs having pointed ends engaging the surface of said helical groove so as to place said sheath and said junction box in good electrical contact with each other and to prevent said electrical conduit from being either pulled from or backthreaded out of said connector; a flange extending outwardly from an end of each of said flexible walls at an angle thereto so as to abut against the outer surface of said junction box wall and limit the insertion of said connector in said junction box wall opening; and two pairs of retaining arms normally flaring out from said flexible walls, each of said two pairs of retaining arms having an inwardly directed tip and being deflectable inwardly to allow said connector to be inserted into said junction box wall opening.
