Aaron, I had the gadget upside down LOL..now that I got it right..I love them..They come 8 in a pack..you simply slide this coiled wire .point first up the hook toward the hook's eye..Then using a needle nosed plier hook the little clip unto the eye..This simply keeps the Horny Toad from sliding backwards..nice invention..I'm sure there are other like stuff on the market..These were 50% off so I bought them....and glad I did.Horny's aren't cheap and I need to preserve them as much as possilbe.
