Abstract: Disclosed is a protective arrangement having elements which essentially consist of concrete and are connected to one another via detachable couplings. The elements of the protective arrangement are arranged in the form of a closed frame.

Abstract: A connecting system (2) for connecting separating elements (1) for traffic areas has two connecting elements (3), each with two juxtaposed legs (5, 6). In each case, one leg (5) of a connecting element (3) is held between the legs (5, 6) of the other connecting element (3) in a positive-locking manner, as a leg (5) of the one connecting element (3) held between the legs (5, 6) of the other connecting element (3) has projections (9, 10) on both sides, which engage behind projections (9, 10, 11) disposed on the legs (5, 6) of the other connecting element (3). The legs (5, 6) of the two connecting elements (3) interlock with their projections (9, 10, 11) in hook form. In this way, the legs (5, 6) are not pushed apart when there is a tensile force acting on the connecting elements (3), but instead are held together or pushed towards one another.

Abstract: A separating element for traffic surfaces, which is preferably made of concrete, has at least one connecting element (5, 6) on each opposite end face (4), via which connecting element the separating element can be connected to an adjacent separating element (1, 20). At least one projection (41, 43) is arranged on one end face (4) and at least one recess (42,44) is arranged on the other end face, wherein a projection (41, 43) is inserted into a recess (42, 44) of an adjacent separating element (1, 20) in order to transmit forces acting in the plane of the end face (4) from one separating element (1, 20) to the adjacent separating element (1, 20).

Abstract: In a concrete safety barrier element (11, 12) with at least one tension member (3) for connection with an end face to another concrete safety barrier element (12), it is proposed for ensuring high degree of safety and simple handling, to provide—as viewed in the operating position—at least one vertical guide groove (22) for a damping element (4) on at least one of the end faces (21), wherein the guide groove (22) includes lateral boundaries (23) for the damping element (4), and wherein the guide groove (22) is configured for insertion of the damping element (4) from the top.
