Sleeved boot and a clamp around the top, or fold the membrane down into the vent like a lead boot.

I've got the technical drawing around here somewhere, but it's actually relatively simple. Imagine a lead boot, then make it out of membrane and install it essentially the same way.

The pic's for a metal sleeve. There's a mod bit sleeve; we get them at Lakeshore Supply.

It goes on just like a lead boot.
