PROBLEM TO BE SOLVED: To eliminate a difference in level at the coupling part of wall surfaces and to provide an excellent concrete wall surface by a method wherein coupling clips to couple together concrete forms made of resin are formed in a shape wherein a U-shape part and an L-shape part are connected together, and the shape and the size of each part are set to respective given values. SOLUTION: Press processing is applied on a round steel having elasticity to a coupling clip. An angle at which a plane containing U-shaped parts crosses a plane containing not U-shaped parts is set to 90-135 deg., preferably 100-130 deg.. A vertical line suspending from a low part of a U-shaped part from the plane is set to 50mm or more and a vertical line suspending from a position is set to 40mm or more. Further, an angleβbetween a straight lineηand a straight lineθis set to 2 deg. or more, and an angleαbetween a straight lineδand lineζis set to±5 deg. or less. A straight line is inserted in coupling clip holes 4 formed in side parts of two concrete forms and the bottom part of the U-shaped part is forced to fall in a direction Y for coupling. This constitution provides a coupling clip which is light and excellent in durability and workability, and excellent in assembly precision of concrete forms.
