  • Such a transfer system for example, in the US 6,402,421 shown.
  • two mobile crash barriers pivotally mounted to permanently installed crash barriers.
  • By pivoting a passage can be created, which serves as a transition for the vehicles.
  • the invention has for its object to provide a crash barrier device whose mobile guard rail parts can be locked better, in particular non-positively.
  • the lock is in the event of a collision of a vehicle, the mobile guard rail elements lock each other so that the guard rail elements remain connected to each other under the influence of greater forces.
  • the guard rail device should provide a better security in the event of a collision.
  • a crash barrier device comprises a first mobile guard rail element, a second mobile crash barrier element and a locking element for providing a lock between the first mobile crash barrier element and the second mobile crash barrier element.
