What a fantastic idea! If you've ever had to struggle trying to loosen a stuck gas bottle you will instantly fall in love with this brilliant idea. The clamp has two screws instead of one and splits in two. To make it even easier you can use a couple of wing nuts so you don't even need a spanner. We have several lady members in Queensland and this would solve their problems. We raised this idea with Jeff and he seemed to like it.  Seen at Crows Nest Qld Club Meet.
