Abstract: A fastener having a resilient body that is formed with a plurality of grips, each of which includes a plurality of teeth for captively holding webs of fabric-like material. Each grip constitutes a corrugated slit that is formed with an opening at each of its ends. Adjacent slits cooperate with one another, when the fastener is disposed in a gripping position, and captively hold the webs in a contour configuration that defines a fitted corner. The openings at the slit ends are operative to facilitate reversal of the fastener position for removing the captively held webs.
