The adapter has a first larger hollow inlet end portion connectable to a source of air, and a second smaller outlet end portion including an elongated tube for insertion in the air inlet opening of the device to be inflated. The two end portions are connected by a smoothly tapered hollow conical portion which directs the air from the inlet portion to the outlet portion and into the device.
