A device for tying and centering reinforcing bars within a cell of a concrete block. A housing adapted to be positioned adjacent the cell contains a tie, which extends from the housing. The tie includes a loop, a free end, at least one centering portion that engages the housing at one end and the loop at an opposite end, and teeth. The at least once centering portion is adapted to position the loop substantially within the center of the cell when the loop is closed around the reinforcing bars. When the free end is pulled, the loop is closed and substantially centered within the cell. Either the housing or the loop itself include a ratchet portion having teeth, which engage the teeth of the tie and hold the loop in a closed position after the free end of the tie is pulled.
