I use the next size of tubing to make barbs. Stick a drill bit in the end and roll the tubing with a razor knife. You can make them as wide as you want. Then solder the piece on the tubing. Doesn't make a big thick barb type of connection but enough to provide a little more diameter/friction. I only do this when I'm not in a hurry. The rest of the time I use zip ties or wire.
