That light gauge L-shaped piece of metal pulls out to release the hose. It has a groove in it that holds the hose fitting in place. There are no threads if you're trying to turn the hose fitting to unscrew it. Grab the L-shaped metal with a pair of pliers and pull. A screwdriver prying between the hose fitting and L will help get it started.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
