PROBLEM TO BE SOLVED: To provide a connection device for filling members capable of surely and firmly connecting the filling members to each other. SOLUTION: This connection device 150 is used to connect the filling members each having a plurality of edge parts arranged adjacent to each other and brought into contact with each other in the water storage space of an underground water storage system and a plurality of connection holes vertically extending through the edge parts. The connection device of a thermoelastic resin molding comprises an upper wall 153, a pair of locking pieces 151 extending downward from the opposed ends of the upper wall 153 and having, at the lower end, an outwardly projecting outer claw 151a, and a pair of holding pieces 152 extending downward from the lower surface of the upper wall 153 between the pair of locking pieces 151. One of the locking pieces 151 and one of the holding pieces 152 are inserted into the connection hole of one of the filling members, and the other locking piece 151 and the other holding piece 152 are inserted into the connection hole of the other filling member. Consequently, two filling members are connected to each other by engaging the pair of outer claws 151a with the lower end surface near the pair of connection holes and bringing the pair of holding pieces 152 into contact with the inner surfaces of the pair of connection holes.
