Name this part?
 

I was installing some heated grips today and managed to snap the plastic throttle grip (long story). I'm after a new one but don't know it's proper name so I can't do a proper search. Does anyone know what it's called?

It's the part that the RHS grip wraps around, that separates the grip from the metal handlebar. It's kinda hard to explain, so here's a photo of it. Or half of it. The rest of the plastic tube is stuck inside the grip.
