You mean the one that is easily made from a small exhaust pipe?

Can be formed using a plumbers bending spring out of a piece of 22mm copper pipe which you can anneal and flare at the end. I made mine that way. A spring will cost you about £4 and 2m of copper pipe about £7 assuming you cannot find an off cut.
