The apparatus has a fork ( 4 ), attached to one end of a rod ( 1 ) and the fork carrying over its both arms a ring ( 5 ), which is provided with an opening ( 8 ). A stiff tongue ( 6 ), which extends up to the middle of the ring, is placed on the ring ( 5 ) in a way that it can be swivelled. The length of the tongue ( 6 ) is approximately 1 to 2 mm more than the distance (a) between the revolving axis (A-A ) of the ring ( 5 ) and the base point ( 10 ) of the fork ( 4 ). Below the fork ( 4 ), the rod ( 1 ) carries noses ( 9 a/ 9 b), provided with slots (E), for clamping the balloon neck (H). After the balloon neck (H) has been inserted through the opening ( 8 ) in the ring ( 5 ), which has been swivelled by approximately 90 degrees, the tongue ( 6 ) snaps over the base point ( 10 ) of the fork ( 4 ) and prevents thereby the springing back of the ring ( 5 ) to its initial position. With this, a single part production, a secure fastening and a space saving storage become feasible.
