Ascend Charlie:
Mine doesn't have any clip-thingyies on the rear edge only the front lower edge. The place it opens up is along the back edge just beside the pax left ear. The door is firmly closed at zero speed but in forward flight the drop in pressure around the body sucks the door outwards along the back edge.
I have thought about some sort of clip but can't see how to do it while still maintaining simple easy opening for rapid egress if I had a bingle. I'm sure someone with a few more active and unscrambled neurones than I have could come up with something.

You have it one
Most of the easy remove systems I've seen are anything but easy.
