[Sailor Steve]

It is a parasol, and I think they were pretty well braced. I looked through the Datafiles on both the Morane and Pfalz versions, and couldn't find any instances of one coming apart in the air, with the exception of the result of battle damage. On the other hand, and to my great surprise, I did find that at least one pilot was killed after going into a spin. I would have thought the parasol design to be inherently stable, but apparently if you did manage to spin one they were exceeding difficult to recover. That trait was shared by most wing-warpers, the Fokker eindekkers being the notable exception.
