Parts for locking sliding screen door

Hello, I have very similar pull latch on my balcony sliding screen door. Looks almost like your latch & pull 84-227 and very similar to your latch & pull 83-116. I am missing a part that keeps the door locked. All I have is just the holes for screws. Could you please look at my photos and let me know if you have the part that will fit. If you don't have it, please advise how to name the piece that I need or how approximately it should look like (screen door strike? screen door latch keeper?). I search all over the internet and can't figure this out. Thank you!
