See the metal strip below? Both terminals are connected. You can connect to either one.

one for flat earth..one for sfera earth..

Show the front also , not just the back, not enough info

Usually doesn't matter if the two earthings are connected to each other. It's just to make it easier for you to do the wiring for tidiness.

Best answer so far.

To have an earthing intact in case one earthing connection is broken by any unlikely event.
To have as low an earthing resistance as possible.
This is basically to have additional and fail-safe earthing in all eventualities.

so which earth to connect?

would like replace current existing one.. but existing only one earth..

Either one also can. Suggest to connect to the one next to L & N so that the wire doesnt have to do a round the world loop.

The far one is usually used to ground metal clad box/metal piping if you are using such things.

thanks..

Your new socket has a metal body/frame thats why got two earth connections, so better to connect both
Just use a short piece of earth/green wire to loop it over to the other earth conn.

omg..another option now.. which best to follow.. lol

The poster Prophecus already explained to you clearly. The rest of answers all "tak boleh guna" one INO. cheers.
