Thanks for posting! The plastic piece you are searching for is a tie bar. This piece helps to guide the tie bar that interacts with the lock on your awning or casement window.

Your guide reminds me of the 39-448 Tie Bar Guide. Carefully look over the dimensions to confirm that this is the correct replacement.
