Cable clamp for coiled tubing

In a well treatment system wherein an electrically operable tool is connected to a remote end of coiled tubing having an electrically conductive cable passing therethrough to establish electrical communication between the tool and surface equipment, the tool having a first longitudinal axis and an inner bore and the electrically conductive cable having an outer surface, the improvement which comprises a cylindrical sleeve having a second longitudinal axis which coincides with said first longitudinal axis and further having a longitudinally tapered slot therein located within the inner bore of the well tool and a split ring clamp having a third longitudinal axis eccentric with said first and second longitudinal axes and further having end portions, the clamp encircling a substantial portion of the outer surface of said cable, said split ring clamp further including radially outwardly extending lug portions extending into said longitudinally tapered slot of said sleeve whereby tension forces applied to said cable cause said clamp and said lugs to move longitudinally within said tapered slot thereby reducing a gap between said ends of said split ring.
