CA 2438211

A tubular coupling member (10) for use in the oil and gas exploration and extraction industries is disclosed. The tubular coupling member is adapted for coupling together lengths of tubing (20) to form a tubing string and includes at least one protective radially extending element (14) disposed on the outer surface thereof for protecting a cable (22) or other medium which runs alongside the tubing string. In a preferred embodiment, the radially extending elements are radially protruding ribs which are equally disposed about the surface of the tubular coupling member.
