Speaker binding posts with plastic covers

My Krell amplifier has speaker binding posts with the clear plastic covers. Apparently these are for EU safety requirements. I want to use spade connectors and have no idea how to open these covers. I’ve wrestled with them but they don’t budge. I don’t even know whether they unscrew or pull out or whether there is some other method at play. Does anyone have experience with these?

Can you not just unscrew them? I think the tabs on the two pieces of plastic 'covers' are there to facilitate that.

They aren't for personnel safety and not required by any code, they are to protect your amp from accidental shorting which is the most common cause of amp failure.  (Everyone says "it just failed!!!").

Usually you can unscrew them with your fingers and put a spade in.

If they just unscrew, then they are very very tight. I'll get some heavy gloves and try again.
