This has been discussed a number of times before, try searching - I even recall a thread where someone dissected a heineken keg to try to determine if it could be made reusable.
Really? I thought they were all the same. I've bought many of Warsteiner German beer in mini-keg format with the built-in spigot. Looks just like a Heineken one.
I wonder how the Heineken min-keg is different?? Off to search....
Here it is... you're right, Heineken kegs are different:http://www.homebrewtalk.com/showthread.php?t=57621
