Coolant leaking, Identified the source just need the name of the part

My engine coolant is leaking from the part in the red circle in the picture.
It will empty out in about 5 minutes, sometimes faster if the engine is hot.
I need help with identfying the part so I can replace it.
I have tried looking online for the part but can not find it.
The left side of the picture goes to the cabin of the car and the right goes to the engine.
I'm not sure if the thing in the red circle is a joint or a connector, but that is where it leaks. There is two hoses that go into the cabin of the car and the one leaking, in the red circle, is the right passenger side one. The other one is next to it, hidden in the picture.
