An annular gap is formed at the front part of the outer periphery of an inner cylinder having a passage passing through it in the axial direction, and a plug main cylinder body is fitted thereinto. A lock ball having a diameter slightly larger than the inner diameter of the outer circumferential side of the tapered hole is loosely fitted into a plurality of tapered holes drilled on the same circumference, with the outer circumferential side having a small diameter and the inner circumferential side having a slightly larger diameter than the outer circumferential side. A compressed air inlet communicating with the gap is formed at the rear of the main cylinder, and a seal ring is fitted into the gap on the inner and outer peripheral surfaces of the rear part, and the seal ring is elasticized rearward by a compression coil spring. The sliding ring is slidably fitted into the sliding ring, and the front outer peripheral surface of the sliding ring supports the lock ball from the centripetal direction and presses the ball in the centrifugal direction. An air-driven pipe joint characterized by forming a slope portion that gradually becomes lower, and further comprising a sealing means facing forward for sealing the insertion side end face of the connecting pipe on the plug main cylinder. . 2. The air-driven blind stopper according to claim 1, which does not have a passage passing through the inner cylinder. 3. A plurality of tapered holes are formed on the same circumference at the front, with the outer circumferential side having a small diameter and the inner circumferential side having a slightly larger diameter than the outer circumferential side. A plug main cylinder into which a large first lock ball is loosely fitted, and a sliding rod loosely fitted into the shaft center of an outer cylinder fixed to the rear outer peripheral surface of the plug main cylinder, and a front outer peripheral surface of the sliding rod. is provided with a slope portion that is high in the front direction and gradually lowers toward the rear, and a second lock ball that is loosely fitted in the rear part of the outer cylinder so as to be movable in the centripetal direction. A deep groove for locking and a shallow groove for releasing the lock of the second lock ball are formed adjacently in the circumferential direction,
Further, a compression coil spring is provided between the outer cylinder and the sliding rod to urge the former forward and the latter backward, respectively, and a sleeve is provided in the outer cylinder to press the second lock ball in the centripetal direction. A compression coil spring biases the connecting tube rearward to allow the fitting to slide freely, and a sealing means for sealing the insertion side end surface of the connecting tube is provided at the front of the outer tube. Features a manually operated blind plug. 4.
