Locking Gas Flap?

[Nigel Willis]

Flap was jammed I tried to use release by pulling ring and complete plastic pull thread came out. Has a smaller ring on working end which must attach to something. Can this easily be fixed?

This is why forum's like this are so great. I too never knew about the locking cover. I checked mine and the mechanism was working but the cover did not lock because the retaining clip had fallen off and down below the cap in the tray. Replaced it where it was supposed to be and it locks again. Great question and information.
