A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.
