A safety intravenous catheter assembly (10), and method for use with a needle (12) is comprised of the following. A catheter hub (18) has an axial bore (20) extending through the catheter hub (18). A needle cover (22) has a first end (24) of the needle cover (22) inserted in the axial bore (20), a second axial bore (26) extending through the needle cover (22), and coaxial with the axial bore (20). A continuous circumferential notch (28) extends outwardly in the axial bore (20) of the catheter hub (18). A notch clip (30) is joined with the needle cover (22), and is positional to engage the notch (28) of the catheter hub (18). The notch clip (30) can engage a side (14) of the needle (12), the notch (28), which locks the catheter hub (18) in engagement with the needle cover (22) when the needle cover (22) is inserted in the axial bore (20), and the needle (12) is inserted in the second axial bore (26) at least adjacent or past a distal portion (32) of the notch clip (30).
