Can someone identify this inside my engine bay?

I found this broken and free hanging today. It is right under the drip stick. It should be connecting to the square metal inside the picture.

Thats probably why your A/C is blowing hot.

thats an a/c line alright. cant tell which one from the photo though.

yes, my AC does not work recently. What might causes it? it is broken like it had taken a heavy impact and got it knock off.

Here is an indication, and shows how the whole piece goes.

that is your low side a/c line to your compressor.
