ABSTRACT:
An apparatus for securing a generally flexible cable to one end of a generally flexible tubular pipe liner which has been impregnated with a thermosetting resin comprises a reinforcing member for reinforcing the liner end to distribute any tension exerted by the liner on the cable. A portion of the liner proximate the one end of the liner is flattened, with the interior liner surfaces interengaging to close the one end and to establish two generally flat liner end portion sides, the flattened liner end portion including a plurality of openings extending therethrough from side to side, the reinforcing member being secured to both sides of the flattened liner end portion. The reinforcing member includes a plurality of openings extending therethrough, the reinforcing member openings being in registry with the liner end portion openings. Fasteners extend through the registered openings in the liner end portion and in the reinforcing members for securing the reinforcing member to the liner end portion. A portion of the reinforcing member extends beyond the end of the liner and includes an attachment member for attaching the cable to the reinforcing member.
