If all you want is a splitter, then tee barbs in tube are the easy way to do things. I'd recommend that you at least think about check valves. They can take care of a lot of interesting "this keg dumps into that keg" sort of things, in addition to reducing the beer guck in your gas lines and / or regulator.
