Abstract (en)

[origin: WO0144773A2] The invention concerns a device (1) for testing the sealed integrity of a chamber (2), in the form of a particular clamp capable of being opened, in functional position, to sealingly enclose all or part of the chamber (2) to define theraround a vacuum release chamber (3). It comprises: a rigid support frame (5) in several sections (10a, 10b) mutually articulated (111, 112) for fixing or removing the clamp on the chamber, said frame being like a U-shaped drip channel open radially inwards, and a jacket (6) made of a relatively flexible material supported by the frame (5) and shaped, at the edges of the drip channel, like deformable sealing lips (16) tightly pressed on the chamber surface.
