Press down on the metal with your thumb to give it a bend, then pull on the other end with your ring finger. I don't recommend ripping it all the way off. If you can't open this, you need to get a physical job.
Don't worry, we are adressing it as we speak. Let's just say my country is also close enough to Germany to adress it as well.
