Abstract: A bag closure clip is provided which consists of a pair of arms, each having a handle at a first end and a jaw at a second end and a hinge mechanism for permitting pivoting the arms to move from an open position in which the jaws are separated to a closed position so that the jaws are together. Another mechanism is provided for biasing the arms to the closed position, so that the jaws are normally together, to make an airtight seal on a plastic bag. When the handles are manually squeezed together the arms will move into an opened position to separate the jaws and release the airtight seal on the plastic bag.
