ABSTRACT:
A jack extension handle assembly that includes first and second elongated segments or extensions connectable together to provide a stable, extended jack handle. At the end of its solid rod-shaped body, one handle extension includes a tapered plug connector. A tapered socket connector at the end of the solid, rod-shaped body of the other handle extension mates with the plug connector during assembly of the handle. The plug and socket taperings account for forging tolerances so as to ensure a proper force-transmitting engagement between the handle extensions. The handle assembly also includes a retainer clip which externally mounts on the two handle extensions to prevent inadvertent separation of the handle extensions during use.
