Broken coolant part. Please help

Long time lurker but I never needed to sign up, until now.
On the way back from the airport on Wednesday night I caught that distinct smell of coolant in the cabin and then the temp started to drift upwards. Long story short I immediately pulled over and realized I had a leak. After closer inspection today, and after removing the reserve lid, I could tell water was leaking out of the attached part. Looks like the plastic has broken off inside the hose. Unfortunately, I can't find this specific part as I don't know exactly what it is. Any help is appreciated.

Thanks!
Details: 2014 Mercades GL450

I've got the diesel so I'm not familiar with your engine, but I think you can find what you need by doing the following:
-go to: https://www.fcpeuro.com/
-enter your vehicle
-on the right there is the categories. You need to go to Engine, Turbocharger, and then Turbocharger Coolant Line

I'm not sure exactly which one you need, but I think you're looking at less than $100.
