Is this the one where the strips may not be original? I seem to recall someone asking about removing strips before.
I think I'm correct in saying that the trim clip that fixes to the bodywork is something like this one in shape:

I removed some clips from the doors I've used on the Sportshatch - to remove the clips, push the centre piece through and that should relieve the pressure on the leg and allow it to be removed. The problem is then retrieving the centre piece from the panel behind.
To remove the strip from the clip, a bit of pressure in one direction allows the edge to clear the clip, then it can be levered away from the body. Use something very flat and wide like a wide paint scraper.
As I write this, I seem to recall that last time we didn't ask whether they were standard strips and that they might not be. Can you post some photos of what you have?
