I had to think about the physics of these things because I would understand that there are inherent flaws in the design. It was easy to twist a bit, but once the "tongue" creeps through when tightening, the handle won't turn. And it doesn't even come with a round tube or hose. How you can use these things is beyond me. Don't waste your time and money, just have a wrench handy and get some regular clamps.
