To easily connect together reinforcements by fitting a clip having a U-shaped engaging part and a restriction part being restricted at the opening part of the engaging part to a crossing part of the reinforcements so as to embracingly hold.

This fixture 1 is constituted so that both leg end parts of a spring steel bent into a U-shape are bent inward, and the U-shaped engaging part embracingly holding the crossing part of reinforcements 2, 3 and the restriction part restricting the opening part of the engaging part are formed. At arranging reinforcements, the fixture 1 is forcedly engaged with the crossing part of the reinforcements 2, 3 squarely crossing to connect them together. Instead of this, a pair of clips are projectingly provided on the right and left of an arc-likely curved top board, and the clips are formed out of an engaging part in which a spring steel is bent similar to the fixture 1 to form a space so as to receive the crossing part of reinforcements and a restriction part restricting the opening part of the engaging part. Hereby, only by forcedly engaging the fixture, they are simply connected together, the working efficiency can be improved, and by using an automatic machine to forcedly engage it, the labor is lightened and the working efficiency can be further improved.
