What is it? -

[CONCH]

Was checking coolant level (still experiencing leakage after dealer replaced the water pump and some hoses & the belts. In shop today). Can someone tell me what this hose end (circled) goes to/is for, and where the clip (arrowed) is supposed to be clipped onto so it isn't flopping around? Perhaps someone has a better picture of how it is supposed to be secured?

Thanks....

And Happy New Year to all.
