3rd brake light/washer nozzle how do I get at it

Had a look at removing then cleaning the rear washer nozzle, but how do I get at it, on my 2011 tourer idtec? Looking up I see two tags that appear to be clips and have got them moving but the lower side of the red lense refuses to budge, any help appreciated.

Got it just got to be brutal, cause was a blockage in the pipe, air line soon sorted it.
