C13/C14 connectors are even known as "kettle leads" in some places.

Commonly referred to as "jug plugs" in Australia.

Kettle plugs in the UK, close enough. I'm not sure if most kettles even use them at this point.

“Kettle lead” is definitely good here too. It is, after all, more than just a plug.

Yeah, I know, I was just giving the colloquial name for them in the UK. We like calling things plugs, including what you might call a socket or outlet. Not exclusively but very commonly.

I'm from the UK (although haven't been there for a decade+) and remember "lead" being used in place of "cable" or "cord" by those around me. Plug would be the other end, which goes into the Mains.
