The Hotellier quick-release fasteners are missing in the AD/SB overview
By default, the Hotellier quick-release fasteners aren't assigned to an aircraft.
If you want to have the quick-release fasteners and the related documents to appear in your AD/SB overview, you have to add a component to the aircraft and choose the quick-release fasteners as the device type. You'll find them when you set the type to Series and search for hotellier.
(Schnellverschlüsse is german for quick-release fasteners)
After you've added the component to the aircraft, you can create a new AD/SB overview, which will now also feature the quick-release fasteners.
