  • a header; and

    first and second clips extending angularly from the header to clip ends, said clips spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod extending lengthwise in a second direction lateral to said first direction and having a generally circular cross section; and

    wherein each of said clips further comprises first and second prongs spaced apart in said second direction, at least two prongs of said clips further defining therebetween a narrow generally rectangular passage extending generally through the clips in the first direction, said passage intersecting at least a portion of said u-shaped opening and sized to receive and confine said notched form tie extending lengthwise in said first direction; and

    wherein in each of said clips;

    at least one of said prongs has flexibility to deflect and facilitate receipt of said notched form tie in said narrow generally rectangular passage by slidably inserting the form tie towards said header between the ends of said clips; and

    at least one of said prongs has a catch positioned such that said clips confine said narrow generally rectangular notched form tie received in the narrow generally rectangular passage; and

    wherein, without clamping, said reinforcing rod and said form tie are restrained against substantial separation from each other, and, without clamping, said form tie is restrained against relative motion in the first direction when said reinforcing rod is received in said u-shaped opening between said notch in said form tie and said header.
