    I recently purchase an AC-11 AC Adapter. On the cord of the secondary (i.e., 6 volt side), juxtaposed to the plug, is a plastic quasi-barrel shaped device. The cord is looped 360° through the device. What is the purpose of the device?

    Theese devices are normal on a lot of different cables for dataequipment. They reduce the amonut of noise from/to the device they are ment for.
