An apparatus is used for adjusting the distance between two opposed form panels and includes a tie rod, first and second nut members, a seat member, a C-shaped clamp member and a bolt member. The tie rod passes through the first and second form panels, and has first and second threaded end portions which engage respectively the first and second nut members. The seat member has opposed first and second sides, and a through hole extending from the first side to the second side. The second nut member has opposite first and second ends. The second threaded end portion of the tie rod is positioned relative to the seat member when the second end of the second nut member abuts against the second side of the seat member. The C-shaped clamp member has two arm portions which engage the retaining cavities of the seat member. The bolt member engages threadedly a threaded hole of the C-shaped clamp member and is rotatable so as to abut against the second end of the second nut member, thereby positioning the second nut member on the seat member when the second nut member abuts against the seat member.
