Abstract: In an element (40b) for introducing shear forces into a concrete body a loop element (43b) is arranged on a shear force mandrel (41b), which loop element has an arc section (47b) in proximity to the surface of the concrete. When the element (40b) is subjected to a shear force (arrow 53) the arc section (47b) transmits this force to the concrete core inside the arc only through tensile forces in the loop element (43b) or in the arc element (47b). To absorb the resulting moment a second arc element (57b) aligned in the opposite direction is advantageously provided behind the first arc element (47b).
