How to change the wiper blades

[zane]

OK - here is a numbskull question. My 2006 LS Focus wipers could do with a new rubber.

The blades on these look like nothing I have had before - and the owners manual shows pictures of blades like those on my old mondeo - not what is actually fitted to the car.

So how do you change them, and is it a whole new unit or can you just change the rubber? (and how do you get them apart??? cheers Zane
