  • Publication number: 20090026766
    Abstract: A pipe clip for fastening a pipe to a wall, ceiling or another support comprises a clip body which can be attached around a pipe. Outwardly extending first and second flanges are formed integrally with the ends of the pipe clip. The head of a tightening element engages with the first flange of the clip body and the shank of the tightening element engages with the second end The first flange is curved with a relatively large radius of curvature in such a way that the free end of the flange extends substantially in the radial direction and the other end of the first flange merges seamlessly in the tangential direction of the clip body. A recess is formed in the first flange for the shank of the tightening element. There is formed in the clip body a recess which adjoins the recess in the first flange and through which the head of the tightening element fits. The clip body is configured resiliently.
