ABSTRACT:
A peripheral portion of a diaphragm is clamped beween respective clamping surfaces of clamping members by means of a band which embraces the clamping members. An abutment on one of the clamping members establishes a predetermined positional relation between the clamping members. In the fully tightened condition of the band, the pressure between the diaphragm and the clamping surfaces of the clamping members is independent of the tension in the band.
