ABSTRACT:
A connector for coupling a conduit to a junction box. The connector includes a one piece elongated body portion having a distal end for receiving the conduit and a proximal end for connection in an aperture of the junction box. A pair of radially projecting flange members are spaced apart at the proximal end of the body portion for straddling the aperture edge wall of the junction box. An eccentric cam projecting from the tubular body portion is rotatable into an interference engagement with an outer surface of the apertured wall of the junction box to clamp the connector in place. The cam includes a screw having an offset head. One of the flange members includes a longer tab portion and an opposing smaller tab portion. The other flange member includes an annular rim.
