The connecting means has adapter means for attachment to the measure and include a resilient seal for engagement within the mouth of the bottle. A tension rod passes through the seal and is threaded adjacent one end to carry clamping means. The other end of the tension rod has means which limit insertion of the rod into the adapter means and enable the rod to be turned and tightened by a cooperating key, whereupon the clamping means clamp against the inside of the bottle and provide positive retention to prevent withdrawal of the seal from the mouth of the bottle except by releasing the clamping means using said key.
