  • Patent number: 8096585
    Abstract: This tubular joint includes a bell end (4) which is equipped with an internal groove (18) and in which is inserted a spigot end (6), a seal (8) and a locking element (12). The groove forms a groove wall (20). The spigot end (6) and the bell end (4) define a radial clearance (J). The locking element (12) includes a fixing tooth (36) and a contact face (28) for application against the wall (20) when the clearance (J) is within a first range of clearances. When the clearance is within a second range of clearances, the locking element (12) forms a rocking point (34) for rocking round the groove wall (20) and the fixing tooth (36) bites into the external surface (22) by a flying buttress effect of the locking element (12).

  • Patent number: 7699355
    Abstract: This variable-angle tubular connection includes a first tubular section (4) which has a flange ring (10), a second tubular section (6) which has an end flange (12) and a clamping device (8) for clamping the flange ring (10) against the end flange (12). The clamping device (8) has at least one linking segment (22), suitable for being applied against the flange ring (10), and components (24) for clamping the linking segment (22) against the flange ring. The end flange (12) has traversing recesses (20) through which the clamping components extend. The end flange is fixed to the second tubular section (6). Application to the sealed junction of tubing elements.
