Internal routing cable sleeve

My new frame comes with internal cable routing sleeves for the gear cables. The sleeves extend up out of the holes in the down tube by around 2cm. My question is how do I 'join up' the gear outer with the sleeve?
I'm sure there's an obvious answer that I'm missing that you guys can help me with - I just don't want to do anything rash like cutting back the sleeves until I know how its supposed to work!
thanks for any help.
