LPG adapter in France

I am soon to take a Warwick XL to France and believe I will need am LPG dish adapter to fill the underslung tank.
I would value advice on which adapter and where to get it please. 
 Mylpg.eu shows a variety of adapters .
Would it be best to wait until I get to France?

You need something like this....

Or, buy three as a kit which covers you all over Europe. 
Imo I wouldn't wait till you get there as some places frown on using adaptors so the less they see the better for you.  
Rich..
Ps. Forgot to say I always use a cheap pair of riggers gloves when filing up with gas as there's a small pressurised release when removing the gun after filling.

It’s worth getting the set, I think.

These look like the business, how do they fit? Does one attach to the LPG pump/nozel or the Moho socket? First time to France for me! Appreciate any advice.
