That's not equivalent because German household breakers are typically 13A, which is less than the 16A that extension cord is rated for. A 2.5A rated Europlug cord[0] is the closest equivalent, but safety standards help there too. Higher-current devices use Schuko, which will not readily plug in to Europlug.
I found an easy way to create an unsafe combination on German Amazon: a Europlug to IEC C8 cord into a C8 to C13 adapter. That's much harder to do by accident than the American version.
