Oh, I see. You're talking about the cassette joint lock tab. First off, I've never seen a plastic one, always metal in my experience. I've never had a problem removing those. Just twist counter clockwise until the yellow dots align, and lift straight off.
If it's stuck, maybe it needs a little mechanical encouragement, but I have never encountered that problem.
