Door Reassembly, Vent Wing Adjusting Rod Retainer

There is supposed to be a retainer to keep the vent wing adjusting rod in place

All it does is provide enough friction to keep it in place during installation

You know the word retainer suggests a mechanical fastener of some sort.

But if the "retainer" is only something to keep the pin in place during installation perhaps the image is misleading and the closed cell foam is the "retainer"
