This is a coolant hose to the EGR valve. It's a little difficult to access but you can do so by lifting up the plastic wire harness and move it a little further so you can get a plier down there to pinch the clamp. Once the clamp is free you can move the clamp forward and then use the plier to grab the hose (put a rag/towel in between) and twist it to free it from the connector. Once it moves freely you can slide it back but you probably won't be able to do so until you lift the valve out of the bore, which is what I did. That's due to the configuration of the coolant lines.
