A method of checking the volume of containers is disclosed according to which a gas is fed into a volume which is correlated to the volume of the respective container and a signal which depends from the fed amount of gas is evaluated as signal indicative of the volume of the container. In order to substantially reduce the time of the measuring cycle at such a method a gas is fed to the volume which is correlated to the volume of the container at a controlled flow, i.e. the mass flow of the gas per unit of time is pre-set in a controlled manner such that it is possible to drastically reduce the time spans during which it is necessary to wait due to transient processes and a chamber which must be loaded in advance will become superfluous.

[ I claim:] [1.] A connector for sealingly gripping a wall section of a substantially cylindrical part of a container, defining a container opening, comprising a connector casing to be applied around said wall section of the container, and at least one pneumatically operated elastically flexible annular bellows arrangement mounted to said casing about a central axis of said annular bellows arrangement, said annular bellows arrangement being pneumatically inflatable in radial direction with respect to said axis so as to be brought into sealing contact with said wall section, independently within limits of the dimensioning and the shape of said wall section.
