A connector assembly includes a sleeve having a first end and a second end. Reinforcing rings are embedded in the sleeve at the first end. A connector, which has a barbed end, is fluidly connected to the first end of the catheter. During surgery, the first end of the sleeve can be cut to exact length after surgical placement. The barb connector on a shunt housing and the cut end of the catheter are brought together such that the barb advances into the cut end of the catheter and at least two rings snap over the barb, thereby fluidly connecting the shunt housing and the catheter while forming a solid attachment and seal.
