This is one tiny 2 wire connector, anyone know the make and part number perhaps?
You didn't specify why you were interested in this information. However, for the reasons Doc mentioned you should probably avoid using these connectors whenever possible. A better alternative for general tinkering/hacking use would be header type connectors with a 0.100" (2.54mm) pitch, examples here. For most of these type of connectors you don't really need any tools beyond a soldering iron and/or a pair of miniature pliers. The also tend to be a bit cheaper than the pluggable type JoeN is talking about, although if you don't mind the slightly higer price pluggables work well in a lot of situations.
