That's a standard Molex 0.093" series. You can actually buy them at Radio Shack (or at least you used to be able to).
Midway liked to use these for their marquee lights. Probably other US makers, too.
03-09-1042 is the mating housing. 03-09-1041 should also work (same thing but with panel locks that you don't need but won't get in the way).
02-09-1205, 02-09-1102, or 02-09-1104 should be suitable contacts.
You can buy those at Digi-Key, Mouser, etc. in small qty.
