Where the hell is the locking wheel adapter on a Mk 6 Astra?

[TNW]

Hi - I've got a Mk6 Astra (latest shape) hire car at the mo. Anyone know where the locking wheel nut adapter lives? Got a puncture and I can't find it. Before I put a rocket up the hire company I just want to check it's not hidden somewhere daft. Downloaded the owners manual, but it's not mentioned - even in the description of how to change a wheel!

Could be anywhere, it is in a small black box, there is no proper place for it to live like in BMWs and audis. Possibly in the spare wheel well or glove box are the most common places.
