There are also Dutch clips which are for straps. http://www.jacksrbetter.com/DutchClips.htm
Dutch, one of the uses I found for those 2nds DCs you gave me (no spring) was to join the two sides of my Snugfit, once I'm inside. The Speer Hammock version of the Snugfit has red grosgrain loops in the center, by the label. I hooked a DC on one side, and after I got in the hammock, I hooked it to the other side. Almost closes the UQ around you, and makes the Snugfit fit a little more snugly! It's easy to remove.
