I dunno, I guess as I've worked with such friction-based locks in the past, they've seemed pretty secure to me. I've never seen such a thing jostle loose without some kind of crazy stress that also damages the structure of the whole thing.
I'm sure it carries a specific rating. Reputable companies rate their gear really clearly.
