I would advise you to do some more research on this. I don't think you will find any chain mfg that will approve of this on 9 speed or greater. As mentioned above, you have now lost part of the pin that holds it in place. It will fail. IF you can find the now deformed pin, replace it with a proper pin or a quick link. If you can't find it, you need a new chain. Concerns about quick links are unfounded as they are included with KMC and SRAM chains and many use them with Shimano and Campy. Plenty of ways to get hurt on a bike, no need to tempt Darwin!
