These are clips of a few different sizes that screw into the wall to help protect outlet plugs from being unplugged. Most drywall screws should work for securing this to the wall - I just used some I had lying around.
The taller clip should fit around outlet plugs like in the second picture, the shorter clip can be used to secure the cable right around the outlet plug.
Happy printing!
