Abstract
The present invention is an apparatus, or plug, for closing an inlet port. The inlet port is formed in a sheet of a typically flexible material. The inlet port is designed to mate with an air hose nozzle. The plug blocks the inlet port when no air hose nozzle is engaged. The plug has a generally planar shape with coplanar extensions extending radially from the plug body. The plug is engaged by causing at least two of the extensions to be received in the inlet port. When the extensions are received, the plug is retained gains the inlet port.
