Patent ID: 8245733

Claim:
A clip of molded plastics material for fitting onto a pipe or duct, the clip comprising an open ring of generally C-shape having facing arms, the facing arms having open ends that can be sprung apart and together to resiliently fit the clip onto a pipe or duct of corresponding diameter, each facing arm having i) a profiled inner surface adapted to engage with complementary profiles carried by the pipe or duct, whereby the clip is held onto the pipe or duct, and ii) an inwardly-directed arcuate rib extending along the inner face of the facing arm and forming a substantially T-shaped profile, the profile having a projecting edge, wherein each substantially T-shaped profile forms in each facing arm a pair of arcuate recesses that are adapted to receive a pair of complementary spaced-apart arcuate ribs carried by the pipe or duct and, wherein the projecting edge of each profile faces inwards and forms part of a generally cylindrical inside surface of the clip, such that when the clip is fitted onto a pipe or duct the projecting edge fits into the complementary profiles carried by the pipe or duct and the arcuate ribs carried by the pipe or duct fit into the arcuate recesses formed in each facing arm, whereby the clip is held onto the pipe or duct.
