ABSTRACT:
A resilient clip with a plurality of twisted wings for engaging a first structure. The twisted wings provide the clip with a low ratio of insertion force to pull-out force, rendering the clip relatively easy to install yet difficult to pull out. In one embodiment, the resilient clip includes at least three wing members that cooperate to prevent the resilient clip from rotating relative to the first structure. In another embodiment, the resilient clip includes an engagement portion having a plurality of teeth for engaging a tab formed into a second structure. The teeth of the engagement portion engage the tab, permitting the resilient clip to be coupled to the second structure. When the resilient clip is engaged to the first structure, the teeth of the engagement portion cannot disengage the tab, rendering the resilient clip non-removably coupling the resilient clip to the first and second structures.
