Part Identification - 2.0 Tdci, Front Of Engine

[V8Darren]

Hi, I need to put a name to a part on my Dad's 2.0 TDCi Focus C-Max. I believe it's a return hose (hard plastic) from the intercooler that goes into a Y piece and into the inlet manifold. Don't really understand why there's a Y which seems to go to both sides of the intercooler, the colder and more dense the air, the better. The hose is identified in my photo with a blue arrow, but the actual part I need is the yellow/green arrow, which is like a rubber seal with an integrated jubilee clip. The rubber has been mullered and needs replacing, most likely during oil changes as the oil filter is in the most stupid place I've ever seen on any engine! It seem like Ford deliberately put things that regularly need attention in stupid places, probably so that the jobs take longer and they can charge more labour time, but that's another story.

Anyway, if anyone could help me name the seal/jubilee clip thingy, that would be great.

Oh, any reason why it would be oily In the hose?
