Injection port connector with rotatable locking lug

An injection port connector comprising;

• a tubular body having a coaxial fluid passage therethrough from a distal port to a proximal port;
• said tubular body having an annular recess around the outside thereof adjacent said proximal port;
• lug shaped locking means integrally formed with a band, said band being deformable to fit into said annular recess on the outside of said tubular body;
• a first and a second coaxial recess forming a first annular shoulder and a second annular shoulder at said proximal port, said first coaxial recess being larger than the fluid passage, and said second coaxial recess following said first coaxial recess and being larger than said first coaxial recess;
• and
• a resilient elastomeric sealing plug constructed to tightly fit said proximal port, said sealing plug begin formed with a first cylindrical section joined by a second larger cylindrical section, said first cylindrical section having a smaller cross-section than said second cylindrical section;
• a coaxial cylindrical blind hole opening in said first cylindrical section, and an annular indentation being formed around the periphery of the end of said second cylindrical section;
• said sealing plug being pressed in said proximal port with said larger cylindrical section having a tight fit with said second coaxial recess, the end portion of said proximal port being bent inwardly to form an annular lip, said annular lip fitting into said annular indentation of said sealing plug, the end of said first cylindrical section being pressed tightly against said first annular shoulder in said proximal port, said first cylindrical section being caused to expand radially against said first coaxial recess;
• whereby said sealing plug forms a fluid-tight self-sealing injection port by axial and radial expansion and said lugshaped locking means is rotatable relative to but not removable from said tubular body.
