Ramdonpanda,
If you haven’t already made your repairs I’d like to pass on a suggestion. If there is a valve on the toilet that has a slip on connector tube then the hose/clamp may not be the problem. The valve itself maybe the source of your leak and the water simply is dripping at the clamp.
I had this happen after my plastic valve was exposure to freezing temperatures. The plastic valve was cracked along the casting line and was very difficult to see until I removed the valve for a closer inspection. The smallest amount of water left in the valve can swell at cold temperatures and crack the plastic.
Remove the valve (very easy to do once the line is disconnected) and inspect the valve closely. Mine didn’t leak until water pressure was applied.
I now use air pressure to blow out my valves and lines to insure they are dry.
Good luck and hope all works out well.
