A cable gland would do the trick. Look them up.
In the end after spending an hour looking at fittings a a DIY store I decided I'm over thinking this. It's just a breather tube for a wild animal house. I'll drill a hole of the correct diameter for a friction fit and leave it at that.
Kim, you are very bad!

Given that that's all out in the open, how come you're using a hose at all, rather than a Mk 1 hole?
Are you sure it complies with building regs? I would go for a more efficient balanced flue approach.
