Didn't snap, those tubes go into a clamp which wasn't properly tightened on either side. The panniers were fairly heavily loaded - 8 bottles of beer, change of clothes and tools, but nothing like the rack's rated limit of 40kg. Glad I discovered this on a one day jaunt to Cambridge rather than somewhere more remote.
ETA: And it's a lucky the rack caught the mudguard rather than swinging all the way off and hitting the floor, which would probably have been no fun at all.
