I was installing my new Rally Armor Mudflaps this evening with the help of this DIY vid:

Here's how you can avoid destroying the clip, and add yet more useless junk into your pile of parts:
The center of the clip will pop out with a Phillips screwdriver, but if you try to lefty loosen it, the entire clip will rotate. Dig under the clip with a flat head screwdriver, and position it so that it will resist the movement caused by your Phillips screwdriver. (You'll need your other hand on the flat head screwdriver, I just needed it free to take the picture).
And voila! It should pop open like the other three clips (at 1:13 of the video) for you to remove with relative ease!
