A clamping assembly for attaching a grounding conductor to a pipe having a protective coating includes an elongate conductive strap and a clamp. The conductive strap is sufficiently long to circumferentially surround the pipe and has longitudinally spaced sharp projections that are sufficient to penetrate the protective coating around the pipe to make an electrical coupling between the strap and a conductive part of the pipe beneath the protective coating. The clamp is coupled to the grounding conductor and clamps the conductive strap to the pipe at a tension sufficient to maintain an electrical connection between the conductive part of the pipe and the grounding conductor without the need for any welding of the grounding conductor to the pipe and without the need for any stripping of the protective coating from the pipe.
