3. The balloon adaptor ( 10 ) according to claim 1 , wherein: the balloon insertion opening ( 22 ) comprises a forwardly diverging conical surface.

4. The balloon adaptor ( 10 ) according to claim 1 , wherein the rear shoulder ( 32 ) is sharp.

5. The balloon adaptor ( 10 ) according to claim 1 , further comprising a one-way valve ( 38 ) located between the inflating opening ( 26 ) and the balloon insertion opening ( 22 ).

6. The balloon adaptor ( 10 ) according to claim 5 , wherein: the one-way valve ( 38 ) is a leaf valve.

7. The balloon adaptor ( 10 ) according to claim 4 , wherein: the rear shoulder ( 32 ) has a neck diameter (D 3 ), the balloon flange ( 18 ) has a flange inner diameter (D 1 ) and a flange outer diameter (D 2 ), and wherein the flange inner diameter (D 1 ) substantially equals the neck diameter (D 3 ), and the flange outer diameter (D 2 ) is substantially larger than the neck diameter (D 3 ).

8. The balloon adaptor ( 10 ) according to claim 1 , wherein: the inflating opening ( 26 ) is adapted to be held by a mouth of a user.

9. The balloon adaptor ( 10 ) according to claim 1 , wherein: the inflating opening ( 26 ) is adapted to be connected to an inflating device.

10. The balloon adaptor ( 10 ) according to claim 1 , further comprising a releasing mechanism ( 48 ), that comprises at least one activating lever ( 50 ) that is pivoted on a pivot ( 52 ) and the at least on activating lever ( 50 ) comprises an operating handle ( 56 ) and a releasing lever ( 58 ).

11. The balloon adaptor ( 10 ) according to claim 10 , wherein: in an inflated position of the balloon and in an un-operated position of the at least one activating lever 50 the releasing lever ( 58 ) gently abuts against a front surface of the balloon adaptor and against the inflated balloon neck.

12. The balloon adaptor ( 10 ) according to claim 11 , wherein: in a releasing stage of the inflated balloon the operating handle ( 56 ) is moved in a releasing direction ( 62 ) and a front end ( 64 ) of the releasing lever ( 58 ) presses against the balloon neck ( 16 ) in a sideways direction.
