Been there - done that.... you have to take the catch apart to re-rivet it in place and then reassemble the catch.
I searched on this forum when mine broke and found someone who posted pictures of each step - but I can't find it nowl. Here are a few posts though that do describe how to get them apart. I can't believe it worked, but it did!!!
Good luck --- if you have time & some patience, the google search function does work --- just gotta try a lot of different things. I searched different combinations of: black, screen, door, catch, latch, plastic.
