Rubbers still got a grip on even with the clamps loose, not unusual. Will any of them twist - without twisting so hard you wreck the rubbers? Can you get a bit of wood in there to lever them off? If you have a hot air gun or a decent hair dryer to warm them might make them a bit more pliable. If you can get a small screwdriver down the side it might break the grip but again need care not to damage the rubbers.
