A device for swaging a ferrule onto the periphery of a cylindrical member includes a first piston mounted for reciprocation within a body and an anvil member drivingly connected to the first piston. The anvil member has a recess at one end to receive an end of the cylindrical member. A camming device is associated with the anvil member for camming a ferrule carried on the end of the cylindrical member into tight peripheral engagement. A second piston is mounted for reciprocation within the body in spaced relation to the first piston. A movement of the second piston is necessary in order to move the first piston. Located between the first and second pistons are an unexpandible chamber which contains a constant amount of fluid and a spring for resiliently urging the pistons away from each other.
