Hi,

Some assistance if poss ; Bought two replacement Bosch wiper blades and struggling a bit. as I don't to damage any fixings etc.

Have tried various non-force methods by lifting, pushing and also small screwdriver under the black flap [pic] with no success.

I assume that they are both secured via the 'Hook' method. As the Bosch installation instructions show this on the packing ....but does not how to remove the existing 

Any help would be very much apprecaited

Thank you Rowley. 

Did try that earlier but maybe the clip  is a bit stiff in the cold weather. 

Will try again now knowing that I should not break anything !!

Thanks again for your help
