Where to buy a shower curtain rod connector

I am moving out of Berlin and realized that the funny 'L' shaped piece used to connect the short and the long rods of the shower curtain is broken ( Picture attached). Checked out OBI and a couple of other Baumarkts, cannot find the connector. Can anyone tell me where I can find one?

Thanks

You either didn't look hard enough or didn't ask at the info desk.

Well, I did both and issue is that the whole shower curtain thing comes as a complete set. I just want the connector.
