Passenger footwell heating pipe fallen off

[olewnikj]

I have a 2010 Fiesta Zetec S (mk7) and I noticed a large plastic tube hanging down in the footwell which seemed to be loose. I moved it slightly to work out what It was and it seemed to come loose. Its a large black pipe which is bent in the middle and at one end has an inlet and the other splits into two. It looks to me like it connects to where the heat comes out into the passenger footwell and the pipe is used to direct the heat into the footwell itself. Can anyone explain to me where the would go back on? .. I tried taking the glovebox out but couldn't see anywhere to connect it back into?
