Abstract: Tool for crimping an element onto a support member, including a movably mounted rod, a first chamber containing a first fluid, a second chamber containing a second fluid, a piston movably mounted inside the second chamber and separating the second chamber into first and second compartments, an input terminal suitable for being connected to a second fluid source, and a main valve configured to direct the second fluid into the second compartment in order to move the piston to reduce the pressure of the first fluid and drive the rod in a direction opposite to a crimping direction.
