Yes, you get them from your regular hardware store. They are often found on the shelf between the skyhooks and the long weights.

They have moved them now, they are with the fork handles.

To be serious for a sec :) plugs are round so the plug can't fall down the hole (on its side) - same reason manhole covers are round.
