ABSTRACT:
A metal or plastic coupling connector (14) is secured to the end portion of a flexible thermoplastic pipe (12) by means of a plurality of thermoplastic plugs (22), (23) (24) which are positioned through access holes (18), (19) and (20) in coupling connector (14) and which are fused to the walls of the flexible plastic pipe (12) to form an integral part thereof. The plugs (22), (23), (24) prevent both longitudinal and rotational movement of coupling connector (14) relative to plastic pipe (12).
