I found out yesterday that standard worm-drive (Jubilee) clips are 'approved' for LPG hose up to 8mm ID (this is 6mm) and 50 PSI, but I also have some bolt type petrol hose clips that I can use if they are a good fit.

We used to use heavy duty cable ties without issue (although not approved) for this purpose... but this was years ago.
