I normally take the view if it aint broke dont fix it but I wonder if fitting these clips before the problem occurs it would make the linkage bulletproof ?
Unfortunately, I already had the problem which I discovered months ago by accidentally brushing against the wiper arm causing it to drop off.

Seeing how this is a 'general problem' with many of our cars, it might be worth a little test. If your wiper arm pops off with only a small amount of pressure applied to it, then it's not particularly safe, so it would be worth applying this fix for a few quid. Or, at least keeping one handy in the car.
The only guarantee is that it will always happen at the worst possible time. We were heading to our first meet in the Lake district and were literally two minutes from home when this occurred.

Fortunately, I carry some zip ties so I was able to apply the video fix below.
There are some
long term fixes - clickety click
and some very expensive fixes can be bought, if you wish to go that way. Whichever way you choose. It's best to be prepared.
