Abstract

The invention relates to an improved system for securing electrical conduit into a junction box. The invention provides a cylindrical insert that its into one of a plurality of tubular projections on the junction box. The insert is slightly longer than the tubular projection and has a diameter sized to slidably fit within the tubular projection. An outer flanged rim on one end of the insert prevents it sliding further into the tubular projection. A split flanged rim on the other end allows the other end to flex together to allow insertion of the insert into the tubular projection. A split inner rim operates in conjunction with a disposable end plug having a conical face that allows insertion of a corrugated electrical conduit to flex apart the other end when it protrudes from an inner end of the tubular projection. The split inner rim snaps into a groove between raised rings of the corrugated electrical conduit and secures it against withdrawal by a pulling force. Any such pulling causes the insert to move with its split flanged rim against the inner end of the tabular projection such that the inner split rim will not release the end of the corrugated electrical conduit.
