Rear screen washer

[Snag20]

Nearly MOT time ( its first with me )

rear washer inoperative---pipe in tailgate is full of green slime/crud.
Hoping to replace the pipe but cannot get it off at the washer jet end.

Thinking that taking the whole jet assembly off would be easier.
How is this fixed on ?? cannot see any nuts etc !!

cheers

if you only want it to work for the MOT
i don't think it needs to, you could just take the arm off and that'll be that
