Where can I find this piece to my charger?

So I had two of these chargers one for my D7000 for my D800E.

The one that came with the D7000 doesn't have this piece where can I get it?

Hi,
I'm in the UK and use this charger with a lead with a 'figure-of-eight' plug on one end, to fit the charger, and a UK mains plug on the other. If I go continental I can swap to a two-pin lead. Can't you do the same with a US two-pin plug an a lead?
Regards, Tony

​perfect thanks!

Good stuff. I've not lost one, yet, but they're so small. It's always possible.
