Do you mean the "D" ring that tightens the QR plate on the camera and then folds flat?
Don't think I'd trust 'em.

That's the one.....I can carry two cameras all day long on dual R-straps and never had a problem. I will check 'em every now and again to make sure they're tight, and I've never had one come loose. I've been using them for about a year now.
