While I was working as a lifeguard, I fiddled around with a few variations on this. I picked up a cat safety collar from walmart and sewed the buckle from that onto some thin 1/4 in webbing I had laying around. That was the best set up I found, the buckle would release, but it needed a pretty good tug. Since then I have seen breakaway lanyards at Office Depot if you don't feel like sewing, though I've never tried these. Hope this helps.<br><br>Chris.
