Thats no Moon, Thats a space station!
I got mine to come off using a bit of force and a big flat balde screwdriver (see the thread linked above).
On hindsight i would of used an open ended spanner to pop them off as it would put even pressure on the clip. please note i did not press anything in on my connectors to get them off and they happily clipped back on to the new filter afterwards.
