So i'm a first timer with chain locks...just used this chain lock on my new O RING chain.

So heres the question:

After slipping the lock over the pins is it normal that theres a 'gap' on the end of the chain lock?

I know that there are tiny slots where the lock should slide in.so i ask if this is normal.

Its not possible the slide the lock more forward,the gap is bent and doesnt nit flex in the slot.

Thanks in advance!

no, the c clip needs to be tight on the pin. go get a new c clip or take it off the chain and carefully squeeze it together with pliers
 
Do NOT try to squeeze it back with pliers! Looks like the chain side plate was not pushed down far enough on the pins, and the clip was installed while not all the way in its groove. Take it off, and if it does not return to its original form naturally, go buy another. This is an unpleasant part to have fail while you are riding! You will probably have to buy a complete master link. On the next try, be sure the side plate is all the way on. You will have to compress the o-rings a little, so it is an awkward process. Unless the side plate requires being pressed on (most do), you will have to keep it compressed with pliers or a vise-grip etc while you install the clip. Remember the open end faces the rear of the bike when on the top run of the chain (like you have it). When installed, it should look exactly as it did resting on the table. The open end should be clipped down tight all the way home in its groove on both sides of the pin with no evident deformation what so ever.
 
That's pretty buggered up. You'll probably need a new master link (I don't think you can buy those clips individually). Good news, they're less than $10. Have a shop or someone who knows bikes show you how to put it on properly.

Chain failure is one of the worst things that can happen. It can take literal chunks out of your body and your bike's cases.

Alternatively, get a riveting master link instead. You would need a chain riveter (which can be expensive) to put it on though, but you'd be able to live without a doubt that your master link won't fail.
 
I've always had good luck compressing the Orings with a vise grip and using Needle-nosed pliers to press the clip into place. One side of pliers rests on the closed end of the clip, the other rests on the tip of the trailing rivet (the one you're trying to get the clip around) or the end of that link.

It helps if you don't have shitty pliers, as side-to-side play can make it more difficult
