Need help connecting two female strips to a female control box

[King Mustard]

I have a control box that has a single female output.

I have two LED strips that I want to power, each has a female input.

I've tried looking on eBay but I can't figure out what I need to buy to get the two strips connected to the single control box.

Can anyone help?

EDIT: Found 5x of what I need for £1.19.

"female strips"

Talk about misleading titles... Anyway how does that little 4 pin header allow you to connect two of those cables into one control box?

I've got a twin control box, not pictured.
