It is a heater hose to core coupling. Some auto supply stores have no clue. I went to Auto Zone and they didn't know what I was talking about and couldn't find anything on their system. Then I went to O'reillys and they pulled it right up on their computer. It cost me $6.00. You can use a large fuel line "quick connect" tool to compress the tabs and release the old coupler from the core. That tool set only cost $10.00 at O'reillys as well.
Are you talking about the aluminum tube that goes from the heater core to the intake? If so, you need to pinch both sides of the plastic retainer, and pull out. Dealer item only.

You will notice the plastic around the heater pipe is connected to some plastic to the front of the car from it. Take a hacksaw blade and cut about a 1/2" groove in that plastic - just enough to get a hose clamp around the plastic circle that holds the pipe. Tighten the clamp and voila! No more leak.
