To provide a connector for a prefabricated block for a civil- engineering construction structure, in which a connected state is not loosened and detached by the changes of a land such as an earthquake and the hanging conditions or the like of load, regarding the connector for a continuous footing and a continuous concrete foundation being capable of assembling and connecting the block simply and rapidly at a site and connecting an end section in the longitudinal direction of the prefabricated block not detached.

Inserting bending pieces composed of a plate material made of a metal are inserted and rotated into punched holes formed to the plate materials made of the metal fixed at the end sections of reinforcing bars for the prefabricated block and the prefabricated block is connected, and concrete or mortar is made to flow into the connector and solidified.
