ABSTRACT:
A tool for inserting a plastic pipe in a substantially axial direction into a stab-type coupling joint fitting or the like without damaging the exterior of the plastic pipe. The coupling joint fitting may be of the type having means therein for gripping the plastic pipe upon insertion of the same therein and also of the type wherein insertion of the plastic pipe activates closure means in the fitting to open the same and provide service. The means for attaching the tool to the fitting and to the plastic pipe are detachable from the tool whereby other means may be substituted therefor depending upon the sizes of the fitting and the plastic pipe upon which the tool is to be used. The actuating means for moving the attaching means for the pipe toward and away from the attachment means for the fitting is screw operated to provide ease of operation of the tool with a lever system providing a large mechanical advantage.
