ABSTRACT:
A molded, one-piece, self-locking, strain-relief bushing for mounting an electrical conductor to a panel having an aperture through which the conductor passes. The bushing is designed to mount the conductor substantially parallel to the panel on one side thereof and substantially perpendicular to the panel on the other side thereof. The bushing comprises two generally concave complementary portions adapted to be folded together in axially offset position over the conductor. One of the complementary portions is frangibly attached to the other and is adapted to be sheared therefrom for self-locking mounting of the conductor to the panel. The busing may be preassembled by hand and self-lockingly installed by a simple hammer blow.
