CA 2394961

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 (11¿1?, 11¿2?) 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.

Dispositif (1) de test d'étanchéité d'une enceinte (2), conformé en un collier ouvrable propre, en position fonctionnelle, à enserrer de façon étanche tout ou partie de l'enceinte (2) pour définir, autour de celle-ci, une chambre de reniflage (3). Il comprend: une armature porteuse rigide (5) en plusieurs tronçons (10a, 10b,...) mutuellement articulés (111, 112,...) pour la mise en place du collier sur l'enceinte ou son retrait, cette armature étant conformée en gouttière à section en U ouvert radialement vers l'intérieur, et un manteau (6) en matériau relativement souple supporté par l'armature (5) et conformé, au niveau des bords de la gouttière, en lèvres d'étanchéité déformables (16) s'appliquant de façon étanche sur la surface de l'enceinte.
