The tube body of the mixing tube 3 passes through the nut 8. A large opening is provided at one end of the nut 8 and a small opening is provided at the other end. The diameter of the small opening is smaller than the diameter of the large opening. A protrusion is provided on the feed end of the mixing tube 3, and the width of the protrusion is greater than the diameter of the small opening of the nut 8.

[0024] When the mixing tube 3 is to be connected to the two-component rubber cartridge 2, the large opening of the nut 8 is placed on the discharge head of the two-component rubber cartridge 2, and then the nut 8 is rotated so that the discharge head gradually penetrates into the nut 8, thereby connecting and communicating the discharge head of the two-component rubber cartridge 2 with the feed end of the mixing tube 3.
