ABSTRACT:
The invention concerns a fastening arrangement between the hose-like neck (11) of a sonde balloon (10) and the closing piece or valve piece (13) of the balloon. The closing piece or valve piece (13) can be fitted inside the hose-like neck (11) of the sonde balloon (10) as gas-tight. The fastening arrangement comprises a fastening ring (12), which can be fitted onto the free mouth part of the neck (11) of the sonde balloon. Hereupon, the outer end (11a) of the mouth part of the neck (11) can be folded outside and over the fastening ring (12) onto the neck part (11) placed on the cylinder part (13b) of the closing or valve piece (13), the neck (11) thereby becoming two-fold. The inner diameter (D.sub.1) of the fastening ring (12) has been dimensioned smaller than the diameter (D.sub.2) of the cylinder part (13b) of the closing or valve piece (13). In this way, against the end (13a) of the closing or valve piece (13), a gas-tight and mechanically reliable fastening arrangement is obtained which is self-tightening by means of the lifting force of the sonde balloon (10).
