The two springs are to hold the chain close together so you can install the conn. link.
It also looks like a riveted chain so you have to mushroom the pin heads after you get it all together. I have a chain tool and it works good for this. It's basically impossible to hold the backside of the link and whack the pin with a hammer hoping to mushroom it out that way.
I've had my chain tool for so long, I think it was made by MotionPro? Could be wrong though. They're all over the net for around 50-60 bucks.
Mmmmm, liquid courage...
