Warmseal double glazing security clips

[loply]

Anybody know how to remove these security clips so I can get the glass out?

Tried the obvious pressing down on the metal tab from the inside, doesn't seem to do anything.

Half tempted just to cut the screws with a multitool, but would rather not.

Cheers for any tips,
Rich

Spring loaded clip, you need someone inside with say a knife to push the clip while someone outside slides it out, once out it all becomes clear on how they work

I tried that but it seemed to do nothing. I pushed the exposed part of the clip away from the glass / towards the frame whilst someone else pulled it. Made no difference

From memory the glass and the clip need to be pushed in as far as possible, from the inside now the clip needs pressing in not pushed back out, this needs to be kept pressed while someone outside slides the clip out, they are awkward I know but if they were easy then they wouldn't be a security feature
