Lose clip location?

[Stuart webb]

Good evening, I’ve recently noticed on my A3 TDI  that the hose support clip/bracket like the one in the photo below is just hanging on the hose, It doesn’t look broken at all but I cannot for the life of me see where it should clip back in, (the photo below is not my car but it shows the same clip/bracket hanging like mine does which makes me think does it clip to the fuel filter housing somehow as the fuel filter has been removed from the car in photo) any help much appreciated.
