ABSTRACT:
An improved connector for coupling an endotracheal tube or the like to a source of gas is disclosed. The connector has an inside diameter which is 21/2 to 3 times greater than the inside diameter of the outlet and is adapted to receive a flexible tube therein. The connector also includes an intermediate portion defining a radially flared outwardly extending annular passageway and a shoulder adjacent to the larger end of the radially flared passageway. The shoulder has a width which is approximately equal to the wall thickness of the flexible tube.
