It is indeed the 90deg bended pipe, but the pipe itself turns in the adapter (not the adapter in the steering rack, which would be ok). So it turns at the red arrow:
Would I have read about this connector is that inside that part it also has an o-ring (or two?) sealing the pipe. Then this adapter is 'crimped' onto the pipe. It seems like this crimping is not effective anymore.
