Help: I cannot find one of these cables anywhere!

I got this cable with my Logitech 2.1 sound set some years ago.

My Dad had one, but misplaced it. My ex has 2 spare somewhere but cannot find them ¬¬. I cannot find one anywhere on the internet, can anyone be of any help?

I use it to connect the RCA jacks from my consoles to speakers.

Not quite the same but will do the same job.

 

There IMPOSSIBLE to find, but if you go to Radioshack or do what Jam said, you can build one.

 

Now why didn't I think of this. Okay, both on order now. I wish people would keep useful cables like this..

 

Found one after e-mailing an ebay shop.
