It is a little hard to describe but I will try. The ones that I have are bendable plastic and they two pieces. One piece fits into the other while pushing a small portion of the tarp into the clip. Once you have the material in the clip you just pull it closed and it holds. It holds very well too because like I said, I have tested them i the winds and the rain and have not experienced a failure yet...sabre11004 <img src="/forums/images/graemlins/smile.gif" alt="" />
