The method of making a catheter with integral Luer locking means including extruding plastic material to form a tube having a relatively thin-walled portion of relatively small diameter and a relatively thick-walled portion of relatively large diameter. The tube is inserted into a heat forming mold having a Luer lock forming portion, and a mandrel, having a Luer taper, is forced into the portion of large diameter to heat form an integral catheter connector portion with an internal taper and an integral external flange having Luer locking lugs adapted for locking engagement with a complementary Luer lock connector. The catheter can be used in a intravenous catheter or cannula placement unit.
