Definitely a trick to it. There's an excellent vid floating around that makes them a no-brainer. I'll see if I can find it.

Edit note: can't find the video, but here's a pic that should help. You can unlock each side of the plastic clip one at a time, once they're both unlocked it comes right off, then you can get the wire clip off easily and the hose comes right off.
