Yep, the charge pipe is exactly the same.
Phil - I've seen a few go like that, from memory the dealer wants £44 as it comes in a set (as sortbilly said). You'll deffo be loosing boost. I had wondered if it was to do with cheap hose clips and overtightening, so I'm sorry if that's my fault, but I can vouch for the clips and I'm fairly sure I didn't overtighten. Plus, looking at your picture, the radial split in the hose isn't in line with the edge of the hose clamp
Edit: Mine you, didn't you say that the dealer had your original charge pipe off for some reason?
Sie and I got some forge hose when ours went - much better although it can be difficult to get it to bend around the mounting for the engine cover. I think I still have some if you fancy a trip over (although I'm away from tomorrow morning).
Another temp fix is some LPG pipe from B&Q which is the correct size.
