This invention pertains to an intravenous infusion set and in particular, a winged needle assembly used for venipuncture having an integral hollow tubular protective member to reduce accidental needle sticks from such infusion set. The tubular member has a slot engagable by the wing on the rotatable hub and needle. Once aligned, the winged hub is pulled back into the slot and disengages at a lock-out position. The lateral notch retains the hub and needle within the tubular member.
