Rear wiper hose popped off

The hose popped off the rear windshield wiper . How do i reconnect it and where does it connect to ? I cant seem to find out . The water just sprays all over because it isnt connected .

You have to keep looking, somewhere in the wiper assembly has to be where it goes and I'm sure its small and hard to see, but is often about 3/4 of the way or more up the wiper itself, and might look like a square or rectangle small box.

Here is a picture of the wiper arm. Hope this helps.
