Abstract
A quick connector is provided for attaching the handle portion of a billiard cue to the shaft portion thereof. The connector includes fittings carried by the ends of the handle and shaft portions. The fitting on the end of the handle portion comprises a cylindrical body having an eccentric shoulder and an elongated central stud on the outer end thereof. The fitting on the end of the shaft portion comprises a cylindrical body having an elongated central bore and an eccentric counterbore on the outer end thereof. The end of the handle portion is initially loosely joined with the end of the shaft portion by inserting the elongated central stud into the elongated central bore and the eccentric shoulder into the eccentric counterbore. Then by twisting the portions relative to each other for a fraction of a turn, the eccentric shoulder cams against the eccentric counterbore thereby causing the central stud to frictionally engage the wall of the central bore.
