I see, Its not really a big deal just a little extra shiny part to throw on that could potentially be a nicesity to have, I could probably make on with some alunimum tubing and two hose clamps, uber ghetto-ify it.

I have also seen the same basic idea but for radiator clamps and fuel line clamps. they have hose clamps inside a housing that looks like a pressure fitted end, Kind of a neat idea for cleaning up the apperance of the bike but not too functional.
