Replacing my speedometer cable

That is normal - you see the little clip at tge end? Take a small screwdriver and pry it away and the gear will slide right off. Now what is wrong with what you’re showing in the pic?
I was the using the pic as a confirmation if i did it right, now if the sleeve that protects the cable has a few cuts in it, is that fine to cover up with like tape or some sort of wrapping or should i try and get that fixed
