I am trying to install a KMC chain with a 'missing link' connector. This one has both pins attached to one side plate and the other side of it is an oval shaped connector that is supposed to somehow slide onto the pins on the other side. It does not seem to me that the oval connector is long enough to slide on and over the pins. What's the trick ???? I have used the ones where there is one pin on each side plate and you squeeze them together to release, this one is definitely different.
