The invention claimed is: 1. A one-piece, open clamping ring serving the connection of thin-walled pipes having terminal flanges, the ends of which are contractible by means of a clamping lock, the clamping ring comprising: an essentially U-shaped cross section with legs (12-14; 22-24; 32-34; 42-44; 52-54; 62-64) provided on the terminal flanges (2, 5, 8, 9a) which are connected with each other via a centre member (11, 21, 31, 41, 51, 61) nearly parallel extending to face edges (3, 6) and which show clamping edges that are projecting in the direction to...
The invention claimed is: 1. A one-piece, open clamping ring serving the connection of thin-walled pipes having terminal flanges, the ends of which are contractible by means of a clamping lock, the clamping ring comprising: an essentially U-shaped cross section with legs (12-14; 22-24; 32-34; 42-44; 52-54; 62-64) provided on the terminal flanges (2, 5, 8, 9a) which are connected with each other via a centre member (11, 21, 31, 41, 51, 61) nearly parallel extending to face edges (3, 6) and which show clamping edges that are projecting in the direction to the terminal flanges (2, 5, 8, 9a), and coming into linear contact with the terminal flanges (2, 5, 8, 9a), and extending in a circumferential direction; a sealing tape (16, 26, 36, 46, 56, 66) with ends (69), the sealing tape (16, 26, 36, 46, 56, 66) disposed into the clamping ring (10, 20, 30, 40, 50, 60) between an inside surface of the centre member (11, 21, 31, 41, 51, 61) and the face edges (3, 6) of the terminal flanges (2, 5, 8, 9a), wherein the sealing tape (16, 26, 36, 46, 56, 66) has a nearly rectangular or trapezoidal cross section and is displaceable in the circumferential direction of the clamping ring (10, 20, 30, 40, 50, 60); wherein a distance between the ends (69) of the sealing tape (66) is less than a distance between ends (68) of the clamping ring (60); wherein a region between the ends (69) of the sealing tape (66) is offset in relation to a region between the ends (68) of the clamping ring (60); a bridge element (67) is disposed in the region of the ends (68) of clamping ring (60), the bridge element (67) being adapted to an inside cross section of the clamping ring (60) and being placed displaceable in the circumferential direction between the inside surface of the centre member (61) and the sealing tape (66). 2. The clamping ring according to claim 1, wherein a distance of the clamping edges (23, 33, 43) measured in an axial direction of the pipes (1,9) is less than a double thickness of the terminal flanges (2, 5, 8) and that the legs (22-24; 32-34; 42-44) of the clamping ring (20, 30, 40) are elastic. 3. The clamping ring according to claim 2, wherein the sealing tape (16, 26, 36, 46, 56, 66) has a substantially rectangular cross-section. 4. The clamping ring according to claim 2, wherein the sealing tape (16, 26, 36, 46, 56, 66) is not firmly connected to the clamping ring (10, 20, 30, 40, 50, 60) and is displaceable in the circumferential direction. 5. The clamping ring according to claim 4, wherein the bridge element (67) is a profiled ring having a U-shaped cross-section, made of sheet metal, and which is inserted between the inside surface of the center cross-member (61) and the sealing tape (66). 6. The clamping ring according to claim 1, wherein the bridge element (67) is a cross-sectionally U-shaped profiled ring made of sheet metal. 7. The clamping ring according to claim 1, wherein the legs (12-14; 22-24; 32-34; 42-44; 52-54; 62-64) have in their cross section a shape of a flat V, an inner section (12, 22, 32, 42, 52, 62) of which being connected to the centre member (11, 21, 31, 41, 51, 61) covers with it an angle of less than 90°, that to this inner section (12, 22, 32, 42, 52, 62) is attached a projecting outer section (14, 24, 34, 44, 54, 64) of an angle more than 90°, and that the joint between these the inner section (12, 22, 32, 42, 52, 62) and the outer section (14, 24, 34, 44, 54, 64) forms a sharp-edged clamping edge (13, 23, 33, 43, 53, 63). 8. The clamping ring according to claims 1, wherein a distance between the clamping edges (13, 53) measured in an axial direction of the pipes (1, 9) corresponds to a double thickness of the terminal flanges (2, 9a) and that the clamping ring (10), 50) is made of a material that is elastically less deformable.
