I may be mistaken but I think the tube you're referring to is a protective outer for the coolant pipe that runs along the bottom of the motor and it doesn't have a clip. There is only a tiny amount of fluid on the photo which wouldn't account for having to top it up. Could it be a random drip from when you were putting the oil in? If you had a leak of any significance your engine would be plastered in it I would have thought.
