Windshield Washer Part

A plastic part that connects the windshield washer tubes on my 1992 Taurus blew apart.
I would like to know what it is, and what it does. It looks like a valve..it doesn't really look to serve any purpose except move the washer fluid along.

Thanks!

That is all it does...Probably has a clog somewhere in the lines. pressure builds up and blew it apart at the weakest point.

Yeah...good news is, it's a 3 dollar part at the dealership...just annoying!
