A molded plastic grip-block and strain relief bushing which is improved by a flare portion through which cable must pass and cannot bend sharply, protecting the cable from flexure stress. The bushing is self lockable in an aperture and comprises a shank including two portions, one of the shank portions being a gripblock, the shank portions defining an opening to receive cable, and having integral means on at least one shank portion to lock the shank portion engaged in said aperture. The flared portion distends regularly from an inside diameter of the flared portion opening to an outside diameter, the inside diameter being in the shank, and the outside diameter of the flared portion being spaced away along the longitudinal axis of the bushing from the inside diameter of the opening no less than a distance equal to .25 of said inside diameter of the opening, the outside diameter of the opening being equal to no less than 1.5 times the inside diameter of the opening. |
