Patent ID: 8424917

Claim:
A moulded electrofusion fitting for connection to a plastics pipeline or spigot, comprising: a hollow body formed with a tubular opening that has a longitudinal axis and is adapted to receive an end of the pipeline/spigot inserted in the direction of said axis as a close sliding fit against an internal surface of the opening; an electrofusion element formed in the internal surface in the opening spaced from its end; fingers on the end of the opening circumferentially spaced around the opening and separated by slots between them; cam surfaces defined on the fingers; and a grip ring received on the fingers and including corresponding wedge elements adapted to fit said cam surfaces of the fingers, wherein a circumferential flange is formed around the fingers to retain said grip ring on the end thereof, wherein said grip ring is snapped over said flange to assemble the fitting, temporarily inwardly deflecting the fingers to permit such insertion, wherein, when a pipeline is inserted in the opening and the grip ring is rotated about said axis, said wedge and cam surfaces engage to press said fingers radially inwardly against the reaction of said grip ring whereby said pipe is gripped by said fingers.
