PROBLEM TO BE SOLVED: To provide a connecting fitting for a separator for concrete forms, by which a cone is not caught at the cut edge of the residual shaft of a clamping shaft and which can be removed easily together with the cut-off of the clamping shaft when the clamping shaft is cut off in a constricting section even in the metallic cone in which the mouth edge of a through-hole inserted to the clamping shaft is formed in a thin shape. SOLUTION: In the connecting fitting for the separator for the concrete forms, which is composed of a fitting body, with which the separator is engaged, the clamping shaft of a male screw projected from the rear of the fitting body for supporting the fitting body to the concrete forms, and the cone inserted to the clamping shaft so as to be interposed between the fitting body and the forms in the case of a use when the clamping shaft is penetrated to the forms and the clamping fitting of the female screw is screwed at the end of the clamping shaft and in which the constricting section as a place broken off after the use is formed at the projecting base end of the clamping shaft, the connecting fitting is constituted so that the cone is formed in a bowl shape by the press working of a metal plate while an inward anti-curved section in which the peripheral-section vicinity of the through-hole of the clamping shaft is pushed to the inside is formed in the cone. In the connecting fitting, the connecting fitting is further constituted so that the through-hole is separated from the constricting section in the case of the use by the formation of the curve in the cone.
