This invention relates to a safety post (101) comprising an elongate tubular member (103) and a locking device (105) arranged inside of the tubular member (103). The safety post (101) is mountable in a post holder (201). The locking device (105) includes a lever (107) and a bias spring device (109) biasing the lever (107) against an inner surface (131) of the wall of the tubular member (103). The lever (107) has a lock protrusion (113) extending through a first aperture portion of the wall, and a release protrusion (115) extending through a second aperture portion of the wall. The release protrusion (115) is arranged at a djstance from the lock protrusion (113). The lock protrusion (113) is retractable to a release position inside of an outer surface of the tubular member by operation of the release protrusion (115) in a counter biasing direction. The release protrusion (115) has a support surface, which is arranged to support the safety post (101) against a support surface of the post holder (201), and the release protrusion (115) is related to the lock protrusion (113) such that, in the release position, the release protrusion is still protruding from said outer surface to an extent. |
