Okay, maybe these pics will help.
Here it is with the clip open. It appears as if the tube extends past the end of the clip, but it doesn't It goes exactly to the end and doesn't hang over.
Here is is with the clip closed. It closes all the way.
Here it is in my hair (dd is napping). You can't even see it because it is on the bottom prong, which is underneath the hair. Invisible!
Does that help any?
