Small panel on front doors

[gold1640]

There's a small panel on the front doors with a 'thingy' behind it, the purpose of which is providing some amusement on another forum.

I've found a diagram that labels the thingy a 'Clip adjustment element', whatever that means.

Anyone know what the 'thingy' is for?

Been laughing at that too.
