1. A subcutaneous tunneling device, comprising
a shaft including a bend;
a catheter connector extending from a distal end of the shaft distal of the bend, the catheter connector comprising:
a body including a gripping portion; and
a barbed extension distal of the body configured for insertion into a lumen of a catheter; and
a sleeve slidably mounted on the shaft, the sleeve having a retracted position exposing the catheter connector to permit a distal end of the catheter to be coupled thereto, and an extended position covering the catheter connector and the distal end of the catheter,
wherein:
the body includes a stepped proximal end attached to the distal end of the shaft, and
the sleeve has an inner bore defining a shoulder configured to abut the stepped proximal end of the body in the extended position, and
wherein:
the body includes a nose stop opposite the stepped proximal end configured to provide an indication that the catheter connector has fully engaged the catheter,
the nose stop includes a lip configured to mate with an outer surface of the distal end of the catheter when the barbed extension is inserted into the lumen of the catheter, and
the lip includes an angled surface extending across the barbed extension.
