Need help finding plug/socket cable connectors

[AppleBite]

Hi guys,

I'm working on a project (a micromouse to be specific), and need an easy way to connect and disconnect some wires. The picture below shows some connectors I took from a computer fan, but I really need connectors with 4 pins instead of two.

Can anyone help me with what these are called (the "plug" and the "socket") and where I can buy them. I don't have a crimping tool, so looking for something with pre-crimped wires.

Thanks for any help,
AB

perhaps This is what you are looking for?

Edit: Under "pin and socket connectors"
