None of the photos above show the correct (uninstalled) configuration of the "legs" of the clip. Photo below shows a similar type of clip, used on '63-'67 Corvette "eyebrow pads" on the instrument panel; you squeezed the "wings" on the clip together with needlenose pliers, and that expanded the "legs" behind the hole, retaining the clip. Once the clip is installed and then the wings are "un-bent" to be removed, most of that feature is lost.
