Zusammenfassung:A barrier system including a guardrail, a support (3) to hold the guardrail in position and a fastener to attach the guardrail to the support is disclosed. The support has a weakened zone (16), around an aperture (13) for the fastener, to facilitate the fastener releasing from the support when the support is subject to impact forces. The zone may immediately release the fastener or initially deform a section (20) of the support delimited by the zone, then release that section. A number of zone shapes and configurations are disclosed.
