The connector comprises a body having a first open end and a second open end for insertion into the opening in the outlet box.

Abstract: A seamless one-piece metal sleeve coupling is adapted at one end to couple with an end of an electric conduit and is flared at the other end to a size larger than the entry opening in an electric junction box. The flared portion of the sleeve has a reduced end portion which is small enough to enter the box opening. An annular shoulder for engaging the exterior box margin about the opening is formed at the junction of the flared portion and reduced end portion. A plurality of outwardly bent gripper arms are formed in the reduced end portion for engaging the interior box margin about the opening. The reduced end portion is split in at least one location and has an expansion joint bridging the split.
