1. A pipe connection structure of an air-conditioning system, the pipe connection structure comprising:
a clip (300) provided on an object (100) to be coupled in which a corrugated pipe (200) is fitted and coupled to the clip (300), wherein:
the clip (300) includes a fixing plate (320) fixed to the object (100) to be coupled, and a pressing protrusion (350) convexly formed in a direction facing the fixing plate (320), and
when an end of the corrugated pipe (200) is inserted between the fixing plate (320) and the pressing protrusion (350) while the fixing plate (320) is fixed to the object (100), the pressing protrusion (350) presses the corrugated pipe (200) so as to prevent the corrugated pipe (200) from being separated, wherein:
the clip (300) includes an extension plate (370) extending from a lower end of the fixing plate (370) away from the object (100), and a support plate (340) extending from an end of the extension plate (370) and erected upward, and
the pressing protrusion (350) includes a plurality of pressing protrusions formed in a height direction and is formed by convexly bending a plate, in which an upper end of the plate extending from the support plate (340) so that the pressing protrusion (350) is accommodated between the fixing plate (320) and the support plate (340).
