sun visor clips

The sun visors unclipped every few kilometers during the pick-up and drive home. I was blind folded everytime which is not funny on the Autobahn!
So, a set of new clips was ordered (as mentioned in another thread) and I installed them recently. First of all I wanted to understand what the problem was, so I did a 1:1 comparison:

No wonder they unclipped! The new clips are much more firm and stop the visors from falling "out of the skies"!
