Where can i find a belt clip like the ones on an iPhone case, but witout the case?

I'm using this to attach my go pro to my swimsuit this summer for some cool footage. I need just the clip part, not the phone case. Any idea where I could find one of these or an alternative that would work the same?

There are many GoPro clips out there, inexpensive and universal. This one seems similar to the iPhone clip:

Well you could go to Amazon they have a huge selection and Walmart has a lot of go pro accessories I know because I own the hero 3
