A weldless spacer for manually connecting without a tool two reinforcement cage wires or re-bars of a concrete reinforcing structure in spaced-apart relation is a unitary resilient wire member that has an elongated spanning portion that extends between the reinforcement wires, a hook end portion at one end of the spanning portion, and a fastening end portion at the other end of the spanning portion. The hook end portion includes a detent part and a V-hook part, which are joined by a spacer loop part and capture one of the reinforcement wires. The fastening end portion includes a detent part and a J-hook part, which are joined by a spacer loop part and capture the other reinforcement wire. One or both of the spacer loops are sized to space the reinforcement wire(s) at a desired distance(s) from the adjacent concrete form wall(s) for sufficient concrete cover. |
