Javier - I just checked my fuel filter mount, which is happily rock solid, and on mine at least the two pieces are "looped" together, so that they will fail-safe in the same way that yours has. It is a tricky area to photograph in, but here's what it looks like as best as I could capture it.

So while this is another case of poor welding (I had a weld fail on the mount for the ignition system in the first few weeks of ownership), it is possible that it left the factory intact.
