A ring binding tool comprising a connection mechanism (6) that includes a connection recess (61) provided with a projection (63) and a connection projection (62) provided with a groove (64). The mechanism serves to connect turning ends (3a) of two turning base plates (3) near their centers to each other so as to enable interlockingly and rotatingly operating the two turning base plates (3). The turning ends of the turning base plates (3) simultaneously come into contact and out of contact with an upper surface (21a) of a recess (21) of a stationary base plate (2).
