ABSTRACT:
A clamping device comprising an elongated wedge body having a bifurcated end, and a second end opposite the bifurcated end. The wedge body is of substantially rectangular transverse cross-sectional configuration, and is relatively thick at the second end, tapering to a relatively thin dimension at the bifurcated end. The wedge body has first and second sides extending between its bifurcated and second ends. Each of these sides carries a plurality of longitudinally spaced, contiguous teeth or serrations over a major portion of its length. The bifurcation in one end of the wedge body defines a pair of spaced, substantially parallel legs, which legs have continuations of the teeth or serrations extended along one side thereof, and are relatively smooth on the opposite side thereof. In a useful combination, the clamping device retains an electrical conductor in place at the location where it enters a knock-out window in a synthetic resin electrical box. The clamping device is wedged between the conductor and the portion of the box which defines the window so that the serrations carried on opposite sides of the wedge body engage, respectively, the synthetic resin of the box and the insulating jacket of the conductor to firmly clamp the conductor in position.
