System Information
Acer ES 17,Windows 10

Blender Version
Broken:2.79b;Hash f4dc9f9d68

Boolean Modifier doesn't divide form from object Netzteil.blend

1.Click the cone-like "cable-holder" with the three rings around.
2.Add Boolean modifier
3.Boolean modifier=Operation=Difference
4.Boolean modifier=Object=Circle.002(selects the three rings attached to the cone)
5.Apply!
6.Nothing happens when the three rings get pulled off!

I created the three rings with a simple circle.
Added a face via "f" in Edit mode.
Extruded it, made it smaller.Deleted the big faces and solidified it.
The half-rings are created with the knife tool.

The rings do not enclose a volume. They all are open on one side. When you close them by adding some more faces it works.

I don't if this is supposed to work though. In some cases the modifier can deal with shapes that are not closed. In general you should always try to use use the Boolean modifier with closed meshes (otherwise it is not clear where the in- and outside is).

I guess this can be marked as invalid as this is more a limitation than a bug.
