Thank you Billsotx for you help. The hook that you pictured in the link is similar, but not quite what I'm looking for. I did do some additional searching for a frog hook and found a picture that shows some hardware that may be exactly what I'm looking for. Take a look at the picture in the third post in this link to see what I'm talking about. It shows both the hooks and the ring that are on the adjustable part of my friends belt. I'm not sure from the context of the post, but it appears that it is the frog hook that you suggested?
