Tubing connector system

A tubing connector system for use between an end portion of a flexible tubing and a tapping hole on a main conduit, the tubing connector system including:

• a single clamp having an adjustable tension mechanism and a flexible band cooperating with the adjustable tension mechanism, the band having an opening to be positioned in registry with the tapping hole, the opening extending between inner and outer side faces of the band, the adjustable tension mechanism including a housing that is rigidly attached over the band and the housing pivotally supporting a worm screw disposed tangentially with reference to the band, the band being wrapped around the main conduit and then closed by inserting an end of the band through the housing and into engagement with the worm screw to form a circular loop encompassing the outer wall surface of the main conduit;
• a monolithic tube fitting forming an internal fluid circuit extending between a tubing fixation portion, over which the end portion of the flexible tubing can be removably inserted with a frictional engagement, and a tapping-hole engaging portion, opposite the tubing fixation portion, which includes a projecting tip part that can be brought into cooperative engagement with an inner peripheral surface of the tapping hole, the tube fitting including a resiliently-deformable flange extending outward and surrounding an outer surface of the tube fitting, the flange having inner and outer side faces with the outer side face being engageable by an area on the inner side face of the band that surrounds the band opening, the flange being larger in width than the band opening;
• and
• a resilient gasket to be interposed between an outer wall surface of the main conduit and the inner side face of the flange to seal a space immediately surrounding the tapping-hole engaging portion when brought into cooperative engagement with the inner peripheral surface of the tapping hole.

• a single clamp having an adjustable tension mechanism and a flexible band, the adjustable tension mechanism including a housing that is rigidly attached to the band and the housing pivotally supporting a worm screw disposed tangentially with reference to the band, the band being wrapped around the main conduit and passing through the housing while engaging the worm screw to form an adjustable circular loop encompassing the main conduit, the band having an opening to be positioned in registry with the tapping hole, the band opening extending between inner and outer side faces of the band;
• a tube fitting forming an internal fluid circuit extending between a tubing fixation portion, over which the end portion of the flexible tubing can be removably inserted with a frictional engagement, and a tapping-hole engaging portion, opposite the tubing fixation portion, and that can be brought into cooperative engagement with an inner peripheral surface of the tapping hole, the tube fitting including a deformable surrounding outer flange, the flange having inner and outer side faces with the outer side face being engageable by an area on the inner side face of the band that surrounds the band opening, the flange being larger in width than the band opening;
• and
