The fixture has a clamping member (5) including a feedthru bore so that correct locking and/or releasing of the clamping member are ensured. The feedthru bore of the clamping member is closed off at one end of the fixture. A locking pin (10) is provided with another feedthru bore for locking and/or releasing of the bore of another clamping member. Each feedthru bore is connectable by a connecting conduit to a compressed air source. A sensor is provided for sensing air flow in the connecting conduit.
