The invention relates to a fitting (70) and a securing component (90) for attaching to a hole in a pipe. The fitting (70) has at least one securing means (90) for sealably securing said fitting to a conduit (106), said fitting having a conduit engaging end (72) and a mounting surface (74) at another end, said fitting being first shaped to cooperate with an external surface (114) of said conduit, said fitting including a first aperture in said conduit engaging end which has communicable passage to a second aperture in said mounting surface, said fitting including at least one sealing surface (82) surrounding said first aperture which is adapted to make sealing contact with a resiliently compressible seal (115), said at least one securing means (90) depending from said fitting to engage an internal surface (116) of said conduit in the vicinity of a hole in said conduit, said at least one securing means (90) when securing said fitting (70) to said conduit (106) compressing said resiliently compressible seal (115) between said at least one sealing surface (82) and said external surface (114) of said conduit and sealing said fitting to said conduit. The securing means has a curved cam surface (94) to compress the resiliently compressible seal (115), and two other cam surfaces (96, 100) of differing radii of curvature to allow rotation of the securing member (90) if the bolt (104) is overtightened.
