The method and two devices of the present invention provide for underground connection of pipe with minimal disruption of the surrounding landscape. The main pipe is cleaned by a surface preparation tool of the present invention designed to access the pipe through a small hole. An adaptor is attached to the second pipe, and then placed in a clamping device of the present invention, designed to access the main pipe and clamp the adaptor thereto through a small hole. Electricity is passed through the adaptor, thereby softening the plastic so that this softening and the pressure of the clamp secures the adaptor to the main pipe. The main pipe is then pierced by the adaptor's tapping tee.
