[TMC] AC power connector name?

[W2HX]

Hello folks, I have a TMC SBE-3 (A-1397) power supply that takes a two prong AC mains input. The prongs are round in shape and male. A picture can be seen here it is J401 (not the 14 pin mil connector on the left, I have that one).

I have seen these before, but I've never known what they are called. If you can tell me what they are called, I can google them and hunt down a female to then wire up to a standard AC plug.  Or maybe you have a spare female?!

Thanks in advance.
