Corner latches

I've been in my home since 1995 but the latches didn't last and easily break if you don't take your time releasing and pulling them out. Pushing them back in is harder because the wire bars inside the edge of the window frame keep popping out at the same time.

I can't seem to find these particular latches. The slide is narrow and the side screw is on the middle.

Please help identify.

Thank you
