a separation wall disposed within said sidewall, said separation wall comprising
a first surface essentially perpendicular to a first portion of said sidewall extending from said separation wall to said first open end of said housing, said first surface forming a closed first end of said first cavity, and
a second surface opposite said first surface and essentially perpendicular to a second portion of said sidewall extending from said separation wall to said second open end of said housing, said second surface forming a closed second end of said second cavity;
a protrusion within said first cavity, said protrusion comprising
an inner surface defining an inner portion of said first cavity, said inner portion comprising an opening for receiving the hub of the male needleless connector in the inner portion,
an outer surface of said inner portion of said first cavity, and
an outer thread on said outer surface, said outer thread being sufficient to interlock with a mating feature of said male needleless connector forming a leak proof seal;
an outer portion of said first cavity, between said outer surface of said inner portion and said first portion of said sidewall, being sufficient to receive a collar of said male needleless connector when said outer thread of said protrusion interlocks with said mating feature of said male needleless connector; and
