The adapter pic shows one of the problems that I see with the Schuko plug in the hands of non-technical people. It's all too easy to plug into an ungrounded outlet.
The strip connectors are common here, where they're often referred to as "chocolate blocks" (because many were brown originally, usually clear these days). They're perfectly acceptable if enclosed in a fixture box, but I'm afraid we see them hanging open like this all too frequently.
