PURPOSE: A pipe connecting apparatus is provided to freely adjust a connecting length of female and male pipes by shifting a connecting port and locker into an inner side of the female pipe to fix the male pipe. CONSTITUTION: A connection port(30) comprise a connecting portion(34), a truncated conical portion(32) and a helical guide rib(36). The connecting portion is connected to a lead of a male pipe(20). The truncated conical portion is extended from the connection portion and decrease increasingly from a large diameter portion into a small diameter portion. The helical guide rib is formed on the outer circumference of the truncated conical portion. A connecting locker(37) is coupled to the truncated conical portion, rotatably moved from the small diameter portion into a small diameter portion along the helical guide rib when the connecting port is rotated in one direction, so that its outer diameter is elastically enlarged to closely contact to the inner circumference of the female pipe.
