Terminology glitch: There are 2 different uses for the word 'toggle': 1. spring loaded cordlocks for adjusting the length of a cord; and 2. short, stiff rods with cord attached in the middle which, when put through a loop of cord, webbing or elastic, hold things in place. That's what you are looking for, I think.
Sorry, I've never found them for sale, so I make them out of whatever is handy. 3/8" Lexan rods and 3/8" hardood dowels cut 1" long with a hole drilled in the middle have worked fine for me. You can go down to 1/4" if you use very small holes (and small cord). Just about anything will work, though - toothbrush handles, chopsticks, whatever.
