<p>PROBLEM TO BE SOLVED: To dispense with frequently replacing a connector eve if the shape of a liquid connector is different and provide a structure for facilitating joint in common by providing an overlap mechanism which can be locked with the respective projecting and recessed parts of the liquid connector of a different shape. SOLUTION: After a liquid connector 10 is inserted in a metal joint 1, a hook part 8a of a lower U-shaped member 7 is hooked on a projecting part 13 of the liquid connector 10 (right half of Fig. 1a). Subsequently, when an arm 4 is turned in the direction of an arrow A to be raised, an upper U-shaped member 6 and the lower U-shaped member 7 are moved in the direction of separating from each other, and simultaneously it is rotated to the liquid connector 10 side round the hook part 8a to be put in the condition shown in the left half of Fig. 1a. Since the upper U-shaped member 6 and the lower U-shaped member 7 are energized to separate from each other by an elongation and contraction member 9 in such a condition, the lower U-shaped member 7 is locked with the locking projection 13, and the metal joint 1 and the liquid connector 10 are firm joined to each other.</p> |
