ABSTRACT:
A Christmas tree type clip for mounting a wire harness or electrical component to a vehicle body panel, the clip being designed to provide a low insertion force and a high retention or withdrawal force. The clip has a hollow, thin-walled, flexible stem supporting a plurality of conventional barbs along its length. The interior of the hollow, flexible stem includes pairs of opposed withdrawal-hindering fingers associated with the barbs such that insertion force exerted on the walls of the stem from the barbs is transmitted to the fingers. The opposed pairs of fingers are angled and spaced from one another such that insertion force spreads the fingers further apart, but withdrawal force exerted on the barbs forces the opposed fingers into withdrawal-hindering contact with one another.
