I need your help! I need to get something that will help me connect two overlapping pieces of hardware cloth in my run. I tried using bits of cut wire but it doesn't seem secure. I have seen many times that people use these metal attachy things. They are small circular bits of heavy gauge wire and you just put them on and clamp them shut with pliers. Does anyone know what these are called? I've explained them at three hardware stores and the employees think I'm nutso, they have no idea what I'm talking about! LOL its gotten kind of funny but if I could find out the NAME of these things that would really help me out!
