A balloon locking cup and securing system includes a cup having a latch interposed between a funnel shaped cup portion and a tube extension. The balloon cup is placed over a reciprocating needle hook rod in a securing system. The tail of the balloon is received by a hook at the end of the hook rod and a first pneumatic cylinder is actuated to pull the needle hook rod in such a manner as to pull the balloon into nesting engagement with the balloon cup. At the end of travel of the first pneumatic cylinder, a second pneumatic cylinder is automatically actuated, causing a knife blade to separate the end of the balloon tail just beneath the tubular member of the balloon cup assembly. The drawing of the balloon into the cup assembly actuates the latch which engages the balloon tail near the neck of the balloon and secures the balloon in the cup assembly.
