Abstract: The invention relates to a reinforcing element for a concrete barrier-wall element, which concrete barrier-wall element has a repelling profile on at least one longitudinal side, wherein the reinforcing element has longitudinal reinforcing bars and has bows, which extend transversely to the longitudinal reinforcing bars and are connected to the longitudinal reinforcing bars. According to the invention, the reinforcing element has at least one first region and the first region largely has the repelling profile. The invention further relates to a method for producing a concrete barrier-wall element having a repelling profile on at least one longitudinal side.

Abstract: A barrier wall element of a vehicle restraint system includes a coupling part having a first leg which has a free end forming a first hook extension and a sliding surface arranged on a side of the first leg. The side faces away from the first hook extension, and a second leg has a free end forming a second hook extension. When coupling the coupling part to an identical coupling part of another barrier wall element, the first hook extension rests in a first contact region on the second hook extension of a further coupling part. The second hook extension rests in a second contact region on the first hook extension of the further coupling part. The first and second contact regions are spaced from one another in a tensile direction of the tension member by a distance which is smaller than a width of the first leg.
