It is a simple thing - a hook for the back to keep grocery bags secure. I have the rear compartment organizer and drive with the rear seats folded to avoid obstructing the rear view. This means when I run out for groceries, I have to drive especially gingerly to avoid slinging the contents of the grocery bags everywhere. These hooks give you something to hang the bags on to help keep them upright and secure. Fits a 2011 - not sure if the vent pattern changed on the later models.
My son printed a pair of these for me for my birthday and they fit great in my 2013 SL.
