1. A bollard comprising an elongate outer tubular cover, an elongate inner tubular core located within the outer tubular cover, a damper located at a lower end of the inner tubular core, a washer arranged to locate the damper against the inner tubular core, one or more spacing elements disposed on an external surface of the elongate inner tubular core, and one or more fixing lugs extending through the outer tubular cover, wherein
the outer tubular cover and the inner tubular core are both substantially circular in horizontal cross-section, the outer tubular cover is able to rotate relative to the inner tubular core, and the outer tubular cover is movable along an axial length of the elongate inner tubular core between a first position with the one or more fixing lugs disengaged from the one or more spacing elements and a second position with the one or more fixing lugs engaged with the one or more spacing elements such that removal of the outer tubular cover from the elongate inner tubular core is prevented. |
