You didn't describe the clips or exact type of shade but parts are relatively easy to obtain, generally.
You can even order a lot of parts for day/night shades through the Amazon marketplace.
Parts for RV pleated Day/Night Shades - Amazon
There are also a few vendor websites you might check too:
RV Shade Parts and Restring Kits
String & Restring Parts for RV Day-Night Shades
RV Day/Night Shade, Parts - FixMyBlinds
There are others but at least you have somewhere to start.
If you don't see what you're looking for on those sites, post a snapshot of the clips that are broken along with any identifying marks and maybe we can match it a bit closer.
