2002 Ford Explorer Pulling out the air filter housing

I am trying to pull out the air filter housing (not sure if that is the correct termanology) to access a "washer fluid" hose that got disconnected. It seems as if the air filter housing should just snap out but no such luck.

What I have done is released the quick disconnects to pull the air filter out and move the air intake assembly aside. This enabled me to access the "air filter housing" that is in the way of me reaching the washer fluid lines. I don't see any nuts or bolts to unscrew. Like I said, it seems like it should just unsnap.

Can someone please help. Thanks.
