ABSTRACT:
An article with a tethered prong fastener having a first stem protruding therefrom, wherein the first stem has a distal end portion with a first resilient arm extending divergently outwardly therefrom and back toward the article, and a first flexible tether coupling the first resilient arm to the first stem. The first resilient arm is flexible inwardly toward the first stem and subsequently flexed back outwardly away from the first stem, whereby the first flexible tether member limits outward deflection of the first resilient arm away from the first stem, thereby improving fastening performance thereof without interfering with the inward flexing of the resilient arm. The tethered prong fastener is configurable as a clip useable for engageably retaining elongate body members, as a w-prong fastener fastenable through an opening in a workpiece, and as a spacing member useable for engaging and retaining first and second workpieces in spaced relation.
