A cartridge for connecting pipes is provided to permit a cartridge cap to be inserted to a collector in any direction, by forming a stepped portion at the cartridge cap for supporting a pipe onto the collector. A cartridge for connecting pipes comprises a collector(10), a convex-concave portion, and a cartridge cap(20). The collector has an inner surface with a groove(11) for insertion of a pipe, and a stepped portion(12) formed on the groove. The collector has an elastic member(13) and a support member(14). The convex-concave is formed at an outer surface of a lower end of an upper support member of the collector so as to prevent the collector from being escaped, when the collector is ultrasonic-welded onto a body. The cartridge cap has an outer surface(21) where an arrow-shaped protrusion(22) is integrally formed in a lengthwise direction so that the cartridge cap is inserted to the collector and fitted to the groove of the collector.
