ABSTRACT:
A terminator fitting useful for connecting corrugated tubing to an electrical outlet box and including a cylindrical collar having first and second ends and a rib projecting radially inwardly from the collar for engaging an external rib on corrugated tubing placed within the collar. The collar carries circumferentially-spaced, axially projecting projections on one of its ends, with each such projection including a wedge-shaped free end portion. Each wedge-shaped end portion is joined to the first end of the collar by a web portion. The web portion, free end portion and collar define a groove for engaging the side wall of an outlet box when the arcuate projections are forced through an opening in the box to secure the fitting in the box. A plurality of blocking flanges are included in the terminator fitting with each blocking flange extending in a circumferential direction from a lateral edge of one of the wedge-shaped free end portions.
