First issue is the the clips must be depressed completely which can be a difficult thing to accomplish while pulling on the hose in tight quarters.
Then pulling the hose off can be tough because they can be stuck on badly after years and years. Just gotta pull real hard.
And sometimes you'll break off the plastic hose because they turn brittle.
