Has anyone ever seen one of these connections before?

Kids are desperate for the paddling pool up but I have bought a foot pump and cannot for the life of me a work out how to connect it, none of the connections seem to fit! I hope somebody can help!

Looks like a big fat round one ought to fit inside (and juts up against the Y-shape).

Our pump has a pointy attachment, a medium nozzle and a big round nozzle. Is that the kind of thing you've tried?

Our air bed has a similar opening. What's your foot pump like? Ours had a tube that fitted into the hole, without any of the attachments on. If your foot pump is like the ones for bicycle tyres etc. with a very thin tube then I don't think there's any attachments that would work.

Can you post a picture of the pump and alltje different nozzles too? Or actually it looks like there might be another bit to be pulled out of the hole on the paddling pool, iyswim? To make a bigger hole?

Think you need something like the largest adaptor here:

Is it supposed to be filled with water instead of air and that is for the hose?

Turns out the pump didn't have the right attachment, who knew that every foot pump wouldn't come with the same attachments, it had to go back and be swapped for another foot pump.
