Type F - Schucko - CEE 7/4

from wikipedia:
The type F plug, defined in CEE 7/4 and commonly called a "Schuko plug", is like type E except that it has two earthing clips on the sides of the plug instead of a female earth contact. The Schuko connection system is symmetrical and unpolarised, allowing live and neutral to be reversed. The socket also accepts Europlugs and CEE 7/17 plugs. It supplies up to 16 Amperes. It is used in Germany, Iceland, Latvia, Finland, Chile, the Netherlands, Norway, Portugal, Spain and Sweden.

"Schuko" is an abbreviation for the German word Schutzkontakt, which means "Protective (that is, earthed) contact".

Although Schuko sockets are unpolarised by design, a de facto standard in most countries is to wire them like the French sockets with live on left and neutral on right, but it is not always observed.
