There is provided a splitting tool for use with a pipe defining a longitudinal pipe axis. The pipe includes an outer wall and an inner wall defining a pipe channel. A ferrule is circumferentially disposed about the outer wall. The splitting tool includes a pipe support member defining an outer periphery that is substantially complimentary in shape to the inner wall. The pipe support member is insertable within the pipe channel to extend at least through the ferrule and to provide radial support to the inner wall. The splitting tool additionally includes a splitter member operatively connected to the pipe support member. The splitter member defines a longitudinal splitting axis that is substantially perpendicular to the pipe axis when the pipe support member is inserted within the pipe channel. The splitter member is moveable along the splitting axis to radially engage with and pierce the ferrule.
