Can anyone point me to some place on line where I can order a detachable key ring?

I bought a new 8 GB USB thumb drive and I want to keep it on my keychain, but I want to be able to detach it rather than having to plug my whole keychain into my computer.

I haven't been able to find anything that is small, however.  Looking for advice.

theres gotta be something on ebay!!!
