Not sure if this model is mine but it looks the same. I have them on sliding shutters and trying to remove. The white tab moves easily but the grey one does not. Is there some trick ? Do both tabs need to be slid over to release ? Don't want to break off.
Thanks.

You are correct, the white tab slides back easily while the grey requires more pressure.. Slide back the white first then the grey. It shouldn't break.
