is received in the cup 36 and the flat bottom surface 26 rests flat upon the top surface 62 of the dovetail slot 12 after properly rotating the dovetail clip 10 as shown in fig8 the final installed position is reflected in fig1 this process can be repeated for multiple dovetail clips 10 being installed within a concrete casting being installed along the same dovetail slot 12 or multiple separate dovetail slots 12 in the final installed position the legs 50 capture the dovetail slot 12 preventing lateral movement of the prestressed cable 14 relative to the dovetail slot 12 furthermore the portions 42 extending into the cup 36 grip the inserted prestressed cable 14 the portions 42 hold the dovetail clip 10 to the prestressed cable 14 if the prestressed cable 14 moves away from the dovetail slot 12 with the legs 50 having a sufficient length to capture the dovetail slot 12 when the prestressed cable 14 returns to its initial position the method as described is preferably accomplished by human force by inserting and twisting each dovetail clip 10 by hand this is accomplished by gripping the first plate 30 inserting the dovetail clip 10 between the prestressed cable 14 and the dovetail slot 12 and rotating the dovetail clip 10 in a until the prestressed cable 14 is received in the cup 36 this method provides for easy installation saving time and money while effectively securing the dovetail slot 12 in a cement cast utilizing the force from stressing the prestressed cables 14 while the invention has been specifically described in connection with certain specific embodiments.
