ABSTRACT:
A clamping bracket connects an electrical wire to a lip of a grounded utility box so as to ground the wire. The bracket has U-shaped portions and a threaded stud which moves an annular abrading end surface with a center cone point into engagement with the metal plate lip when located between the U-shaped portions. The rear planar member of the U-shape is formed by a leaf spring which slants inwardly and bends rearwardly until the leaf spring is approximately parallel with the front planar member due to engagement of a stop surface on the stud with the front planar member. A plurality of barbs located on the leaf spring assist to prevent inadvertent movement during tightening. The front planar member of the U-shape has side ribs which strengths the front planar member and space a threaded bore from the metal plate lip.
