Unknown Item in Case Accessory Box

[maklabouhlel]

What is this accessory I keep finding in my case accessory boxes:

 

[RJC]

Looking at the manual its Lock bracket for the side window / panel.

But does not show how to install.

 

[SilverTongue]

looks like an anchor point that you bolt on to lock pc down to stop it being stolen
