ABSTRACT This invention relates to an apparatus for testing the gas-tightness of joints between hollow bodies, for example, pipes.With the apparatus, a test space with two concentric chambers of variable sizes is formed. The outer one is filled with a gaseous test medium and the inner one with an incompressible pressurized medium. It is thereby possible to reduce substantially the quantity of the gaseous test medium. The safety of the entire apparatus is improved extraordinarily.
