Claim Text:
1. A tubing connector system for providing a removable air-tight and water-tight sealing connection under high vacuum conditions 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 forming a circular loop encompassing the main conduit and having opposite inner and outer side faces, the clamp including an opening, extending between the inner and outer side faces of the band, to be positioned in registry with the tapping hole; 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 flange extending radially outward and located adjacent to the tapping-hole engaging portion, 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; 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 tapping hole inner periphery; and a slide clamp to constrict the end portion of the flexible tubing in a withdrawal-resisting frictional engagement with the tubing fixation portion, the slide clamp including an annular sleeve portion and a plug portion.
