An intravenous device, comprising: a needle adapter, a catheter assembly, and an introducer needle, wherein: the needle adapter has a proximal end, a distal end, an outer surface and an inner compartment; the catheter assembly includes a catheter tube coupled to a catheter adapter, the catheter assembly further including a luer adapter coupled to the catheter adapter via an extension tube, the extension tube being flexible, and a fluid pathway extending through the catheter tube, the catheter adapter, the extension tube and the luer adapter, wherein the catheter adapter is partially housed within the inner compartment of the needle adapter while the luer adapter and the extension tube are entirely housed within the inner compartment when the device is fully assembled; the introducer needle has a proximal end, a distal end and a body extending therebetween, the proximal end being coupled to the proximal end of the needle adapter and the distal end extending beyond a tip portion of the catheter tube, wherein the body of the introducer needle extends through the fluid pathway of the catheter assembly; and a safety clip interposedly positioned between a proximal end of the luer adapter and the proximal end of the needle adapter, the safety clip having an aperture through which the introducer needle is inserted, the safety clip further including an arm having a first surface interlockedly coupled to the luer adapter, and a second surface in contact with a surface of the inner compartment, wherein contact between the second surface of the arm and the surface of the inner compartment maintains the interlocked coupling of the first surface of the arm and the luer adapter. the needle adapter has a proximal end, a distal end, an outer surface and an inner compartment; the catheter assembly includes a catheter tube coupled to a catheter adapter, the catheter assembly further including a luer adapter coupled to the catheter adapter via an extension tube, the extension tube being flexible, and a fluid pathway extending through the catheter tube, the catheter adapter, the extension tube and the luer adapter, wherein the catheter adapter is partially housed within the inner compartment of the needle adapter while the luer adapter and the extension tube are entirely housed within the inner compartment when the device is fully assembled; the introducer needle has a proximal end, a distal end and a body extending therebetween, the proximal end being coupled to the proximal end of the needle adapter and the distal end extending beyond a tip portion of the catheter tube, wherein the body of the introducer needle extends through the fluid pathway of the catheter assembly; and a safety clip interposedly positioned between a proximal end of the luer adapter and the proximal end of the needle adapter, the safety clip having an aperture through which the introducer needle is inserted, the safety clip further including an arm having a first surface interlockedly coupled to the luer adapter, and a second surface in contact with a surface of the inner compartment, wherein contact between the second surface of the arm and the surface of the inner compartment maintains the interlocked coupling of the first surface of the arm and the luer adapter.
