Abstract:
1. A fitting for attachment to a membrane, said fitting comprising a mounting adapter to be secured to said membrane, a resiliently deformable part associated with said mounting adaptor and arranged to embrace and hold an initially separate insert, in which said resiliently deformable part is a cylindrical element and the initially separate insert comprises a substantially cylindrical portion, the cylindrical portion having an outer surface having an outer diameter and the deformable cylindrical element has an inner surface with an inner diameter which allows the cylindrical portion of the insert to be inserted into the resiliently deformable element, the deformable element being arranged such that when the mounting adaptor is secured to said membrane and exposed to pressure exerted by fluid at one of two sides of the membrane, the inner surface of the resiliently deformable element is urged into gripping engagement with the outer surface of the cylindrical portion of the insert, wherein the resiliently deformable cylindrical element comprises a sleeve for receiving the insert, said sleeve joined by a radially extending web to an outer cylindrical part of the mounting adapter and the outer cylindrical part is substantially rigid relative to the resiliently deformable part.
