A friend of mine who is an organic chemist showed me a technique that they often use to hold down various "lids" such as rubber septa and other things onto flasks. It is a very simple design that works amazingly well and is cheap.
You just get a maybe 8" piece of solid copper wire (some scrap from household wiring projects works well) and fold it in half. Then, you twist the folded end up a ways, create a loop around your carboy neck and twist the other end tight. The non-looped end is a bit sharp, but can be filed a bit or covered with tape. I just leave mine as-is and use caution when handling the carboy.
Then, you can loop as many rubber bands as you want under the copper twists and over the carboy bung, etc. to hold it down securely. Works great for when the bung wants to pop out when it is wet with StarSan or when there is a heavy blowoff set up on it. I use more than one rubber band in case one breaks for some reason. Now you can be confident that the bung will stay in place no matter what!
The reason to use copper wire is that it will not rust and make a mess over time.
