Tilt clip part

Hello! The part you're looking for is called a tilt latch. I'm confident we can supply you with a good replacement option, but I can't tell what you have from the provided photos. Can you remove an undamaged version of this latch from the window and show us a couple pictures of it by itself? I'd especially like to see its sides and bottom, in addition to a picture of the top, of course. That would be a huge help, thank you!

I still can't really tell what you have without seeing an undamaged version. My best guess from these photos would be our 26-243 and 26-244 but you should make sure that our dimensions match yours before you commit to a purchase.
