On both sheds I've had problems with these. The flimsy springs that
are part of them come loose, and the P things come free. Does anyone
know of a better latching system made for these kind of doors that I
can look for? A link, a name, whatever I can use to help find what I
need would be great.

Lee Valley might have what you're looking for. They have quite a few types
in their hardware catalogue.
