Claim 0:
1. A syringe adapter comprising:
a housing having a first end and a second end positioned opposite the first end, the housing comprising
a first portion enclosing an interior of the housing comprising an annular planar wall, a recessed vertical cylindrical wall, and a plurality of vertical ridges extending radially outward from an outer surface of the recessed vertical cylindrical wall, and
a second portion comprising a wall enclosing the interior of the housing connected to the first portion, the first end of the housing comprising a connector configured to be secured to a syringe barrel;

a cannula positioned within the housing;
a seal arrangement positioned within the housing and movable through the first and second portions of the housing, the seal arrangement comprising a membrane; and
a protective cap connected to the second portion of the housing via a snap fit, the protective cap comprising an open first end, a second end, an annular sidewall extending between the first end and the second end, and an annular shoulder extending radially inward from the annular sidewall and proximally from the second end of the protective cap, the annular shoulder having an end intersecting the annular sidewall distal from the first open end of the protective cap and another end intersecting the second end of the protective cap,
wherein the annular planar wall of the first portion of the housing directly contacts an annular top surface of the wall of the second portion providing an axial interference, which restricts pulling the first portion away from the second portion of the housing and pushing the first portion farther into the second portion of the housing, and
wherein the recessed vertical cylindrical wall and plurality of vertical ridges extending from the recessed vertical cylindrical wall of the first portion of the housing directly contact an inner surface of the wall of the second portion providing a radial interference, which restricts twisting of the first portion of the housing relative to the second portion of the housing.
