1. A catheter assembly, comprising:
a catheter hub having a distal end to which a catheter tube is connected, a proximal end and a wall having an inner surface defining an internal fluid passageway, a transitional step provided within the internal fluid passageway;
a septum having a distal end and a proximal end having a surface, the septum positioned within the internal fluid passageway such that the distal end of the septum abuts the transitional step;
a septum retainer having a distal end and a wall having an outer surface, the outer surface of the wall of the septum retainer and the inner surface of the wall of the catheter hub respectively configured to interlock with each other when the septum retainer is fitted into the internal fluid passageway, the distal end of the septum retainer in abutment contact with the proximal end of the septum, an aperture at the distal end of the septum retainer providing an opening to the surface at the proximal end of the septum.
