Abstract: PURPOSE:To secure airtightness between a liquid leakage inspecting device for brake hose, etc., and the mouthpiece of a hose when the device is press-contacted with the mouthpiece and an inspection fluid is led into the hose so as to prevent wrong discrimination by providing a means which applies tension to the hose in the device. CONSTITUTION:A brake hose W is suspended by means of the suspending click 13 of a supporting base 13 and the base 8 is moved to an inspecting position side by energizing a tension applying cylinder 11. As a result, the base 8 comes to the inspecting position. When the base 8 comes to the position, the hose W becomes almost straight due to the tension applied by the energized cylinder 11. Therefore, when a fluid leading port 5 comes into contact with the mouthpiece of the hose W, both of them are tightly adhered to each other. Then the rod 4a of a cylinder 4 for sealing protrudes and a fluid leading means 5 moves toward the base 8 holding the mouthpiece Wa. As a result, an airtight condition is maintained between the means 5 and mouthpiece Wa and, when a liquid is led into the hose for inspection, no liquid leakage occurs due to wrong connection. The connected state can be discriminated by means of a sensor 12.
