Abstract
A needle connector assembly for attachment to an IV receptacle which includes a needle hub with a cannula or needle attached thereto and a housing to which the needle hub is mounted. The hub has a plurality of equi-spaced splines thereon and the housing has an aperture in the rear portion thereof defining a plurality of equi-spaced slots therein which mate with the splines when the hub and the housing are secured together. Along the length of the interchangeable splines and slots, an inwardly projecting, one-way barb is provided which has an inclined or cam surface at its leading edge. When the hub is inserted into the housing, the needle is completely surrounded by the housing and the barbs bite into the adjacent material to preclude withdrawal of the hub from the housing. The housing and the receptacle may interlock with each other at a patient IV site to secure the housing to the receptacle.
