A first lever and a second lever are hinged to each other by a pivot. Each lever includes a handle at the bottom end and a jaw at the top end. The jaw at the top end of the first lever includes a curved portion and a tip portion, as does the jaw at the top end of said second lever. The pivoting arrangement of the first and second levers is such that the handles are squeezed together to move the respective jaws of the first and second levers together to surround and compress the plurality of fingers on the spring retainer.
