A balloon neck fitting to be attached to the neck of a balloon sold by a balloon vending machine. The balloon neck fitting consists of a check valve section and a guide section, and these two sections, though initially joined together, will be separated from each other when the associated balloon is inflated and delivered from the vending machine. The check valve section is fitted in the neck of a balloon and serves to prevent backward flow of the gas from inside the inflated balloon, while the guide section serves as a guide when the neck fitting is moved within the vending machine. The check valve and guide sections separated from each other have been tied together by a string and the guide section serves as a hook for the finger when the purchaser carries with him the balloon.
