Abstract
An improved clip of unitary construction for sealing an object, such as the valve of a balloon, flexible tubing and the like, is disclosed. The clip has first and second clamping arms connected by an integral hinge the interior of which defines an interior clamping area. The interior surface of the hinge has a series of fine ribs which aid in retaining the object within the clip and in creating an airtight seal. Both the first and second clamping arms have first and second C-shaped flanges at their extended ends, the flange of the second arm being larger than the flange of the first arm and having an inwardly directed lip which locks the first flange within the second flange, thus locking the clamping arms together and retaining and sealing the object within the ribbed interior clamping area.
