The peritoneal dialysis catheter includes a thin, flexible tube, a catheter connector at a distal end of the tube, and a cylindrical cover surrounding at least a portion of the catheter connector. The catheter connector includes a tip that is configured to attach to a dialysis tubing assembly. The tip can include an externally threaded surface. A peripheral wall of the cover can surround or shield the externally threaded surface of the tip. The peritoneal dialysis catheter can include a cap, which can be removably attached to the tip.
