ABSTRACT:
A method of and apparatus for pulling pipe involves providing a pipe having an exterior surface with a groove circumscribing the exterior surface of the pipe adjacent to one end and an anchoring collar which is segmented into segments and has an inner circumferential surface with an inwardly projecting tongue. The segments of the anchoring collar are secured together to circumscribe the pipe with the inwardly projecting tongue engaging the groove of the pipe. One end of the pipe is capped with an end cap. The end cap is coupled to the anchoring collar. A tow line is secured to the end cap and exerts a pulling force, with the anchoring collar securing the end cap against removal when pulled and the end cap preventing debris from entering the pipe.
