Clip holder?
Thanks for posting! The clip hold you are searching for is referred to as a screen knife latch. The tab on yours resembles either the 70-226 Andersen Screen Latch Pair or the 90-227 Large Butterfly Latch Pair. To determine if either of these will be a fit for your screen, you'll need to remove them and carefully compare the dimensions and design.
There is a video tutorial tagged below with instructions on how to remove and install these latches.
My apologies for the misunderstanding! I'm sorry to say we would not be able to provide you with a replacement for the screen strike you have here. My best suggestion would be to reach out to a screen and window repair shop in your area; they may be able to provide you with some guidance about where you can find a replacement.
Our sincerest apologies that we could not be of help with this part of your repair but please don't hesitate to reach out with any other questions you might have.
