A bridging member is detachably secured to and bridges the arms. A first die part is secured to the free end of the piston and a second cooperable die part is secured to the bridging member. The die parts cooperate together to swage the sleeve onto the bars by the movement of the first die. piece toward the second die piece in accordance with the movement of the piston along said longitudinal axis.
