ABSTRACT:
A nozzle for inflatable objects being made of a plastic material, including a nozzle seat which is subject to engage with the inflatable object in such a manner that it is normally retracted in the inflatable object but also being extendable from the surface of the inflatable object when being pulled out; and annular wall extended from the nozzle seat which defines an air inlet; a plug for insertion into the air inlet; a plug arm extended from the annular wall and connecting the plug with the nozzle seat; a plug extension extended from the plug at a position remote from the plug arm and having two holes; a tie at a side of the air inlet opposite the plug arm being passable through the two holes on the plug extension; and a piece of one-way membrane extended from a lower face of the nozzle seat which during inflation allows air to blow in through the air inlet but which blocks air from flowing out of the air inlet when the nozzle seat is protruded from the surface of the inflatable object.
