For the pin locks, the original style holds best. There is a spring that holds each joint tight. The retainer slips over the pin, into the groove and the lip is bent down so that it can't come out. The other modern style of clip is much thinner and tends to bend under the spring pressure. The originals are difficult to buy from description. I ended up buying some of different sizes to find out which one fit.
