The plastic hook and elastic band provides tension for the corner of the convertible top liner that came on Boxsters, I believe after MY 99.
The hook is supposed to fit under and around the silver metal horizontal bar that is at the base of the B-Pillar on each side. You've got to put the top in the service position to reattach it.
