Abstract: A clip 10 for an electrical wiring harness of a vehicle comprises a gapped annular body 12, the end portions of which are adapted to interengage in overlapped relationship to close the body. The end portions are provided with abutment means 48,50; 52,56 and 58,60 which prevent transverse relative movement of the end portions when they are so interengaged. In this way the risk of disengagement of the end portions is avoided.
