It's like captainobeys says, it's not in the block very tight. First I would remove the alternator to get good access. Then use a thin blade screwdriver and try to pry up on the oil tube. Just get under that flare part and pry up and grab it with a pliers. I was expecting the worse, but mine came out easy! Good luck.
The photo shows the seam where the tube breaks. That lip (flare) gives you something to work with and keeps the tube from dropping down into the oil pan.
