I recently purchased two sets of the Bosch Micro Edge windshield wiper blades. I became concerned during installation when I realized that the universal adapter does not have anything that hooks into the slot of the windshield wiper arm to keep it from pulling off. I have installed them on Subarus. The Bosch website indicates that the preinstalled adapter is the correct one. Could anyone provide direction if something was done wrong during installation or why the safety catch from the adapter to the wiper arm slot is not needed?
