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 connecting device (2) for connecting separating elements (1) for traffic areas comprises two connecting elements (3), each having two limbs (5, 6) arranged next to each other. Each limb (5) of a connecting element (3) is positively received between the limbs (5, 6) of the other connecting element (3) in that a limb (5) of the other connecting element (3) received between the limbs (5, 6) of the one connecting element (3) has protrusions (9, 10) on both sides, which engage protrusions (9, 10, 11) arranged on the limbs (5, 6) of the one connecting element (3). The limbs (5, 6) of the two connecting elements (3) engage in each other in a hook-shaped manner with the protrusions (9, 10, 11) thereof. In this way, the limbs (5, 6) are not pushed apart when a tractive force acts on the connecting elements (3), but instead are held together or pulled together.

Abstract

A connecting device for connecting separating elements (1) for traffic areas comprises two connecting elements (3) which positively engage with each other on at least two connecting regions (13, 18; 14, 15, 16). Each connecting element (3) has a main plane (11), and the connecting regions (13, 18; 14, 15, 16) are located behind one another when viewed in the direction of the main plane (11). The connecting elements (3) are caught in each other in the connecting regions (13, 18; 15, 16), thereby preventing the connecting elements (3) from bending toward the side when a tractive load is applied as a result of a collision, and thereby at the same time preventing the hook-shaped connection of the two connecting elements (3) from being detached.
