The seal around the valve on my mattress has failed after being in storage. What's this part of the mattress even called, and can it be repaired?

Edit: thank you for your helpful comments. To answer my questions:

What's the part called?:

The search term "inflatable mattress nozzle" yielded results on some sites.

Can it be repaired?

I don't have a high level of confidence, but I'm going to try anyway!
