Abstract
A fastener snaps through aligned apertures in two work pieces. The shape of the aperture in the first work piece is such that the fastener cannot be withdrawn from it. However, the aperture in the second work piece is so shaped that the fastener can be rotated for removal of the fastener from the second work piece. The work pieces thereby can be separated, but the fastener remains in substantially permanent association with the first work piece for reuse of the work piece and the fastener.
