Scaffolding element for a scaffold, wherein the scaffolding element comprises a scaffolding tube having a convex outer curvature and a node point, wherein on the node point a) a crossbar of the scaffolding element is connected to the scaffolding tube and/or b) a coupling point for coupling a crossbar is formed, wherein the scaffolding tube comprises a first stiffening notch in the region of the node point, the stiffening notch extending in parallel to the central longitudinal axis of the scaffolding tube as a concave recess having an curvature towards the interior like the before outer curvature, such that the inner curvature of the first stiffening notch corresponds to the outer curvature of the scaffolding tube, wherein the scaffolding tube comprises a second stiffening notch in the region of the node point being parallel to the first stiffening notch, wherein the inner curvature of the second stiffening notch corresponds to the outer curvature of the scaffolding tube, wherein the first stiffening notch covers a first section of the outer circumference of the scaffolding tube along a circumferential direction corresponding to an angular section between 20° and 40°, preferably 30°, with respect to the central longitudinal axis of the scaffolding tube, wherein the second stiffening notch covers a second section of the outer circumference of the scaffolding tube corresponding to an angular section between 20° and 40°, preferably 30°, wherein the first section and the second section, and thereby the first and the second stiffening notches, are directly adjacent to one another, wherein the first and the second stiffening notches are formed similar, and wherein a portion of the scaffolding tube is adjacent to the second stiffening notch, the portion not being deformed concavely, but having the normal convex outer curvature of the scaffolding tube. a) a crossbar of the scaffolding element is connected to the scaffolding tube and/or b) a coupling
