The invention relates to the field of automobile air conditioners, in particular to an air-conditioner pipe. An air suction soft tube and the tube body of a liquid hard tube are locked tightly through a plurality of hoops in order that parts of the outer walls of the air suction soft tube and the liquid hard tube are pressed against each other; the air suction soft tube and the tube body of the liquid hard tube are locked tightly through a plurality of tube clamps in order that a set gap is kept between parts of the outer walls of the air suction soft tube and the liquid hard tube; a protection blanking cap is arranged on the end part of the air suction soft tube; an O-shaped sealing ring is arranged on the outlet part of the protection blanking cap; a first expansion valve blanking cap is arranged at a joint between an expansion valve and the air suction soft tube; a second expansion valve blanking cap is arranged at a joint between the expansion valve and the liquid hard tube; the first expansion valve blanking cap and the second expansion valve blanking cap are fixed at two ends of the expansion valve through bolts. The air-conditioner pipe is installed and limited through the hoops and the tube clamps, so that tight clamping of the air-conditioner pipe is realized, and the phenomenon of falling is avoided. The expansion valve and the expansion valve blanking caps which are unique in structural design are provided, so that a refrigerant in the air-conditioner pipe is effectively protected.
