Went to get the alloys off a C4GP and came across the locking wheel nut - nothing unusual there, except there is no adapter!
There are hundreds of different ones but this one is new on me. Looks like it will have four offset studs inside.
Anyone come across these and can point me in the direction of the correct adapter.
I think that's broken, half of it has been ripped off. my advice would be to go to a good tyre firm and get them to take it off with their special tools.
My local tyre man had all four off my C5 in about ten minutes..............and they went in the bin, they're a bloody nuisance.

That looks to me that the locking head has sheared off. I know that you say all four are the same, and that suggests to me that the locking bolts have been put back in by an ignorant gorilla at a bodgit tyre place (either so tightly the heads sheared, or could no longer be undone). I would suggest you take a trip to your local scrappy, and see if they can help. When (on my C5) one bolt (still with the main head attached) wouldn't come loose (and broke the 'key', but fortunately the other three bolts had come out) I believed they could help. In a large bucket in the tyre section they had a large number of 'keys' from all makers, and with various lug combinations. I was able to find a couple that fitted, but (in my case) that did not help (they still got the bolt out though).

During my garage business days,Locking wheel bolts,or should it be F***ing wheel bolts? have cost me more grief,time wasting,aggro etc etc than all the other car problems put together. They are a complete waste of money.When was the last time someone had their wheels stolen? These days you're more likely to be mugged and they drive off in your car.
Get a good tyre man or a thread doctor to remove the debris and replace them with normal standard wheel bolts.
If you look at the image I have linked to, you can see that there is a point where the 'head' narrows. It is here that a bolt will shear, as it is not meant to take a socket (it helps keep the 'key' aligned). What I think you have are bolts with the 'head' missing, but with the rest of the bolts remaining;

I think it MIGHT be possible for a 'key' to undo it (if you are lucky), as there appears to be enough for the key to hold onto (but you would want a rattle gun, and a lot of weight on it, to try and shake them loose). Otherwise it may need a specialist.
Good luck.

Check in the glovebox and the tool store under the rear floor, they key might just be in there. I've just binned the ones on both my cars. PM me your address and I'll send you the keys, one of them just might be a fit. Otherwise, a reverse spiral socket may just get enough grip on the ring at the back to get them out. Otherwise try your local tyre place; I expect they will have enough aggressive tools to get them off. I got 8 bolts for 12 quid on e-bay.
I've looked in every nook and cranny there is - nowt, zilch! I do have one for another set of bolts and my brother has a different one but neither go anywhere near this. I have a decent set of Irwin extractors, it's just a question of how tight the monkeys have rammed them on.
There was a guy on here before with a similar problem - he rather ingeniously parked the offending wheel adjacent to his garage doorframe and used a scissor jack against the doorframe to wind on an extractor tight onto the rounded nut. This gave him the required pressure onto the nut so the extractor didn't slip off or round off the nut even more.
