A spacer is provided for locating a reinforcing cage or fabric, with respect to a form, when manufacturing reinforced concrete articles such as piping, manhole sections, walls and the like. The spacer is formed from a single length of heavy gauge steel wire, and includes a mounting section which wraps around a longitudinal rod of the reinforcing framework and abuts a transverse rod at its junction with the longitudinal rod. An intermediate section of the spacer extends transversely from the mounting section and is approximately parallel to the transverse rod. A hook at the end of the intermediate section remote from the mounting section is positioned to latchingly engage the transverse rod responsive to elastic deformation of the spacer, thereby to securely maintain the spacer on the reinforcement framework. A spacing loop of a predetermined dimension is provided along the intermediate section.

An apparatus suited for removable attachment to a concrete reinforcing framework, said framework including a plurality of parallel and spaced apart longitudinally directed first frame members and a plurality of parallel, spaced apart and generally transverse second frame members, said frame members connected to one another at a plurality of junctions, said apparatus including: a unitary spacing member constructed of a flexible material and having a mounting section positionable in surrounding relation about a selected one of said first frame members, with a first end portion of said mounting section positioned against a selected one of said second frame members on one side of the junction, the entire mounting section being positioned on the same side of the junction, such that the mounting section can slide toward the junction until the first end portion thereof engages the second frame member at the junction; an intermediate section at least one twice as long as said mounting section, said intermediate section extending from an inner end, which is connected to a second and opposite end portion of said mounting section, to an outer end, the intermediate section and mounting section defining a reference plane, said intermediate section including a spacing means directed generally normal to said reference plane with an apex positioned a predetermined distance from the reference plane; and a latching means at the outer end of said intermediate section for forming a latching engagement with said selected second frame member, the latching means terminating at a position short of the second frame member when the spacer is in an undeflected position, the latching means engaging and latching the outer end of the intermediate section on the second frame member when the spacing member is resiliently deflected toward the second frame member, the engagement of the first end portion of the mounting section with the second frame member restraining the spacing member from sliding laterally toward the second frame member when the spacing member is urged toward the second frame member, the mounting section resisting compression while at the same time restraining the intermediate section from pivotal movement toward the second frame member without resilient bending and deflecting, the engaged latching means in combination with the engagement of the first end of the mounting section with the second frame member holding the spacing member in a resiliently deflected position, the residual force of the resilient deflection tending to maintain the latching engagement and secure the spacing member on the framework.
