摘要

The coupling device (2) for attachment of a pipe (4) comprises a tubular seating section (6) and an annular component (8) which is sealingly joined to the seating section and is inflatable so that it presses against the pipe to be attached and forms a seal with it. An independent claim is also included for an engine test bed with one or more fluid lines incorporating at least one coupling device corresponding to the one proposed above.
