Are you talking about the white plastic clip that goes on the cable? I have attached a picture below. If that is the broken piece, it can be purchased separately.
The part number from Dorman is 14908. This can be purchased anywhere online like Amazon, or from your local auto parts store.
I have also attached the shift cable replacement procedure below.
Please let me know if you have any questions.
