dsk,
That device almost looks like one of them cheap travel adapters that you can buy from the usual suspects on the Internet.

One thing I really hate about using anything like this, is that they are usually a compromise in not only mechanical strength, but also the connections inside these devices are often not made with the same current-carrying capacity and end up with a sloppy connection at best, which will eventually cause a fire safety hazard.

In my opinion, any sort of adapters should be banned, the world over.
If you don't have the correct socket-outlet or the correct plug, ask yourself why niether of them are present and make the required changes.
