Abstract: A two-part fastening mechanism employing (1) a continuous metal strip having attachment slots whose axes are oriented parallel to the length of the strip, and (2) a single preformed metal connector piece having a longitudinally-oriented hook for gripping one end of a tile and a stem portion insertable into one of the slots in the metal fastening strip and bendable over the slot and back upon itself for retaining the connector piece attached to the continuous metal strip. When installed, the fastening mechanism holds each tile in two places: at a first end via the hook, and at an opening in the tile where the connector piece passes through.
