Looks like behind the engine closer to the battery’s side this tube snapped or a connection is missing? My coolant was spilling out one day after a drive. I found the location. I’m just not sure what I am missing.

 

Search the forum on "heater hose connector". No, never mind, just read this thread:

Replaced mine this weekend. All good now but it was quite difficult to get the broken coupler out. It broke apart and pieces fell deeper into the hoses. Getting the hoses out was also quite challenging. Ended up putting thick cardboard on top of the engine and laying on the cardboard to get at it. Turned the engine on and it shot coolant out with broken up chunks of the coupler. Fun times. Still super happy it wasn't the water pump.

No, the heater hose connector has snapped. It's right there in the pic.

Also, you can't tighten a constant tension band clamp. That doesn't make sense.

Also also, the OP made his post last month then never came back to the forum, which is kind of strange.
