Extractor fan rectangle adapter won't fit

Hey, I wanted to install an extractor fan in the bathroom into an existing rectangle vent opening in the wall. I bought these adapters but it seems I'm missing some connection piece between them and I can't find it. The are all exactly the same size and I was sure they would plug one into the other... https://preview.redd.it/zp616eb3bd5f1.png?width=1516&format=png&auto=webp&s=489a610ebcab69893d5fbc6fafbefc5c47fd4156 https://preview.redd.it/f4mgrln6bd5f1.png?width=1516&format=png&auto=webp&s=9feba3db7d0ac96285014eb5e0a58dc8680a6a3a https://preview.redd.it/w1hiu7yxad5f1.png?width=1516&format=png&auto=webp&s=8d03e6b7deca41b90dc8aadc46916882cd1212a0 I think I'm missing some kind of rigid sleeve that should go over the fan and round adapter, and also a rectangle sleeve that goes over wall mount. Am I right? I tried searching it in the stores but can't find anything that matches my description. The fan and round piece are 125mm, the rectangle mounts are 220x55 mm. I also saw a rigid long rectangle duct but I'm not sure if it will fit into the adapter, it might be also the same size. https://preview.redd.it/c54z1v2oad5f1.png?width=1146&format=png&auto=webp&s=702ccd997b37ff825f1eb2ad5e974ee13e356d82 Can anyone help with more info?

Hey,

I wanted to install an extractor fan in the bathroom into an existing rectangle vent opening in the wall.

I bought these adapters but it seems I'm missing some connection piece between them and I can't find it. The are all exactly the same size and I was sure they would plug one into the other...
