Am I missing a part?

[blue2000s]

My 2000S has a hook built onto the door that will hold the cap by the tether strap.

I was at a tech session with 2 old time Boxster owners. Both are the original owners of 2000s. One has the hook and the other does not. One is older than the other. The newer 2000 has the hook. So some time during model year 2000 production Porsche switched over to the fuel lid with the hook.

Neither of these cars came with the gas cap with the tether. They had the gas caps with the slots like my 1997. Both were subject to the recall and the sloted caps replaced with the 2001 style cap.

You can see cbennet1's picture of a 2000 has no hook, while your 2000 does. I would bet your car is newer.

The hook is useless without the tether. They'd have to be added together.
