My straps on my 30lb bottles were always a little hard to close. Finally broke the clamp on one so went to Camper Clinic and bought a new strap which came with a new clamp. The new strap was just a little loose so I took an old bicycle tire tube and cut a short length and wrapped it around the new strap to take up the slack. Is now tight and clamp closes nicely.
