Hi
I was ready to make a spark plugs renewal following Haynes guide.
But when I disconnected the breather hose from the air cleaner housing-to-throttle body duct, one of the connections of the plastic retaining broke

(a little plastic tube with an almos insignificant hole in it)
Now I have to find this spare part, but I don't really know how to call it or what to ask for.
I 've been googling spare parts in many english and french pages but they dont seem to have it. Or at least they don't have pictures of it.
Does anyone know how and where I can get one of them and what I should ask for?
