ABSTRACT:
A connector for affixing a flexible conduit having external helical grooves to an electrical junction box is disclosed. The connector comprises a stamped and formed metallic retaining clip in conjunction with a rigid housing. The clip engages the helical grooves and also establishes contact with a circular hole in one face of the junction box. Both a secure mechanical and electrical connection are established so that the metallic conduit and the metallic junction box can serve as a continuous electrical ground. A straight-through and a right angle version of the connector are disclosed. The retaining clip is mounted in the housing so that the connector snaps into the circular hole and can be removed without damage.
