Probably worth a try, but as others have said it looks a little thin and noose like. Right now I am using a leather snap cock ring for pseudo clamping, but it is not going to good forever, as the snaps don’t allow for much in the way of subtle adjustment like a cable clamp does.
However, I am with you on the cable clamps though — personally I have not got confident enough in my ability to release them quickly. I must be stupid or something.
That is why I am looking into maybe investing in Monte’s air clamps if I get more serious about clamping — that looks like a great device. Comfortable, easy to get out of. See about midway down on the product page:
