The fastener has a second shape wherein the distal end segments are spaced apart from each other along substantially an entire length thereof. The fastener has a third shape wherein the distal end segments bend towards each other so that they are adjacent and form the fastener into a second loop, wherein the second loop has a width greater than a width of the first loop.
