An improved over-the-needle catheter assembly is provided with means for facilitating one-handed separation of the catheter hub from the needle hub. The improvement comprises providing the catheter with a top outside surface presenting a generally smooth surface interrupted by a depression. The depression has a bearing wall for transmitting a force component applied by the finger of a user; such force component having a distal, coaxial direction with respect to the catheter hub.
