What is the name of this plastic piece?

As requested, getting back to you. Followed your instructions, my doors don’t lock me out.

On my ‘69 Valiant, both the driver and passenger door will not lock unless the door is CLOSED. That means you have to..

1. Lock it from the inside
2. Lock it from the outside with the key
3. Lock it from the outside with the window rolled down
