ABSTRACT:
A hose repair connector apparatus is set forth for the repair connection of various pipe, including an elongate flexible hose, including flexible drawstrings directed circumferentially proximate each end of the hose through circumferential slots. A modified embodiment includes a polymeric sealing ring underlying each drawstring, wherein each drawstring is captured within a pocket between the ring and exterior portion of the hose. A further modified embodiment includes a plurality of coaxial flexible hoses secured together by heat seaming at proximate terminal ends thereof, with a pneumatic valve directed into a chamber defined between the exterior and interior hoses to create back pressure against a rupture in an existing pipe.
