Tevo Little Monster Extruder tube connector replacement

The white one in the image is the printed part, printed using white PLA, better print it with a stronger filament, mine broke in a week, thank god I already printed 2 of them. The black one is the original part. I don't know what this part is called, please suggest me in the comments section. My part was loose and didn't have proper threading, which makes the filament extrusion difficult. So I designed printed and used this replacement part.
