when your running a commercial cave winter is slow.....we got several keychain biners (that had a actual notch for the halves to meet in) and stress tested them. They did surprisingly well. You could slowly load them to about 450 lbs. You could gently bounce them (frogging) up to about 250lbs. but a shock load of even about 75lbs dropped 2 feet would break them every time :)
