CONNECTOR FOR WATER PASSING BLOCK, AND METHOD FOR COUPLING WATER PASSING BLOCK

PROBLEM TO BE SOLVED: To provide a connector for a water passing block, which eliminates the risk of breakage even when the coupled water passing blocks are displaced and which enables the water passing blocks to be also coupled and connected together by being put into a bent state, and a method for coupling the water passing blocks together by using the connector.SOLUTION: Both side parts of a pipe-like connector body 4 are constituted as insertion parts 8 capable of being inserted into ends 2A of a water passage 2 of a water passing block 1, respectively. A water sealing protrusion 9 for being brought into intimate contact with an inner surface of the water passage 2 is provided on the outer peripheral surface of the insertion part 8. The plurality of water sealing protrusions 9, which are each formed in a shape having a length in the circumferential direction of the outer peripheral surface of the insertion part 8, are provided in a juxtaposed state at intervals in the insertion direction of the insertion part 8. The water sealing protrusion 9 is made of a flexible material such as a rigid rubber.
