ABSTRACT:
A clamp for attaching a pipeline tracer wire to a pipeline riser has an elongated riser grip which is resiliently flexible to snap onto the riser. An elongated conduit with a V-shaped groove extends integrally along the outer wall of the riser grip. The conduit receives the tracer wire therein. At least one tap screw is engagable in the groove and radially into the conduit to lock the tracer wire between the screw and the opposite inner wall of the conduit. Alternatively, a tap screw may be threadedly engaged in the upper end of the conduit to lock the tracer wire between the screw and the opposite inner wall of the conduit. Preferably, the clamp is made of non-metallic, fire retardant material such as a high density thermoplastic.
