PROBLEM TO BE SOLVED: To easily clamp a trolley line by providing a pair of molding bars having substantial J-shapes in cross section with leg side lower ends as ears for holding trolley line and a steel rectangular coupling plate for fixing top sides of the molding bars butted each other and making it possible to clamp the trolley line by leg side lower end ears by fastening bolts. SOLUTION: When a trolley line T to be corrosion resistant rigid body electric traction to be used in areas containing salt and sulfur content in the atmosphere such as a coast and a hot spring is clamped, a pair of phosphor bronze molding bars 1, 1 having J-shapes in cross section are provided. When top sides 1a, 1a each other of the molding bars 1, 1 are butted, the trolley line T can be clamped between teeth parts 1c at a lower end of each leg piece 1b. The molding bars 1, 1 butting the top sides 1a, 1a each other are fixed with a plurality of bolts 3 by using a reversed angle coupling plate 2 which is a copper alloy with spring rigidity, preferably, phosphor bronze rectangles. In the fixing state, the trolley line T is surely clamped and fixed by fastening of the legs 1b, 1b with bolts 4.
