For reasons I dont wish to go into, I need to get a plug for this connector:

No identifying marks at all on the connector (I have both ends - but need some more of the female sockets) to work out who made it.
How do I go about plugging stuff in? My idea was very small crimp spade connectors but my Dad reckons thats "dangerous" (wiring is used for a very low-power car amp).
Is there any company who will be able to make up a female version of the connector block, and what sort of price it would be?
