Patent ID: 7661730

Claim:
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 , 9 a ) 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 , 9 a ), and coming into linear contact with the terminal flanges ( 2 , 5 , 8 , 9 a ), 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 , 9 a ), 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 ).
