The window wiper has stopped working on the passenger side. Is it fairly straight forward linkage on these or more complex?

Thanks

If the linkage has come off at the ball pivot point, for a quick work around, Halfords and others sell a repair click - Halfords Windscreen Wiper Repair Clip | Halfords UK

 

I've never needed to use one, maybe others can comment on that to keep you moving until you buy a new linkage or just trust the repair clip.
