A resinous tube has opposite ends into one of which a mating member is fitted and with which the mating member is connected, and includes a sealing ring, a fastening cap, and a clamp. The sealing ring is disposed on an inner peripheral surface of the opposite end, and contacts elastically with an outer peripheral surface of the mating member. The fastening cap is disposed on the inner peripheral surface of the opposite end on an outer end side thereof with respect to the sealing ring, and contacts elastically with the outer peripheral surface of the mating member. The clamp is disposed on an outer peripheral surface of the opposite end, which is provided with the fastening cap on the inner peripheral surface, and tightens the fastening cap. The resinous tube exhibits good sealing and fastening abilities, requires less component parts, and can be connected with any mating members.

1. A resinous tube having opposite ends into one of which a mating member is fitted and with which the mating member is connected, the resinous tube comprising:a sealing ring being disposed on an inner peripheral surface of the opposite end, and contacting elastically with an outer peripheral surface of the mating member; a fastening cap being disposed on the inner peripheral surface of the opposite end and exterior to the sealing ring, and having an inner peripheral surface around which a projection part is formed in a ring like manner, the projection part contacting elastically with the outer peripheral surface of the mating member; a clamp being disposed on an outer peripheral surface of the opposite end, the opposite end being provided with the fastening cap on the inner peripheral surface, wherein said clamp acts to tighten said fastening cap and to thereby fasten said mating member; and a ring disposed within said resinous tube and interior to said sealing ring, wherein the opposite end is formed of a thickness sufficiently thin so as to be capable of diametrically enlarging, and said sealing ring and said ring are brought into contact with the inner peripheral surface of the opposite end elastically by the diametrically enlarged opposite end, said projection part is not pressed onto and not brought into contact with said mating member when the mating member is fitted into said opposite end, and said projection part is pressed onto and brought into contact with said mating member by tightening up said fastening cap with said clamp after the mating member is fitted into said opposite end. 2. The resinous tube according to claim 1, wherein said fastening cap has an inside diameter equal to or slightly smaller than an outside diameter of said mating member.3. The resinous tube according to claim 1, further comprising a stopper portion for inhibiting said mating member from being further fitted into said opposite end upon contact therewith, the stopper portion being disposed within said resinous tube interior to said sealing ring.4. A connecting mechanism for fastening a mating member with a resinous tube, the connecting mechanism comprising:a sealing ring disposed on an inner peripheral surface of an end portion of the resinous tube for contacting elastically with an outer peripheral surface of the mating member; a fastening cap disposed on the inner peripheral surface of the end portion and exterior to the sealing rinse, the fastening cap having an inner peripheral surface around which a projection part is formed in a ring like manner, the projection part for contacting elastically with an outer peripheral surface of the mating member; a clamp disposed on an outer peripheral surface of the end portion, wherein said clamp acts to tighten said fastening cap and to thereby fasten the mating member to the resinous tube; and a ring disposed within said resinous tube and interior to said sealing ring, wherein the end portion is formed of a thickness sufficiently thin so as to be capable of diametrically enlarging, and said sealing ring and said ring are brought into contact with the inner peripheral surface of the end portion elastically by the diametrically enlarged opposite end, said projection part is not pressed onto and not brought into contact with said mating member when the mating member is fitted into said opposite end, and said projection part is pressed onto and brought into contact with said mating member by tightening up said fastening cap with said clamp after the mating member is fitted into said opposite end. 5. The connecting mechanism of claim 4, wherein said ring includes a stopper portion for inhibiting the mating member from being further fitted into the tube upon contact therewith.
