The invention relates to a flexible coupling comprising a lower assembly (10) having a spigot member (20), and an upper assembly (60) having a recess adapted to receive the spigot member, thereby allowing articulation of the upper assembly (60) with respect to the lower assembly (10) in any direction. A complementary indexing means is adapted to circumferentially align the lower assembly (10) and the upper assembly (60), and a single resilient member (65) interconnects the lower and upper assemblies, wherein the lower and upper assemblies are urged into mutual engagement against said articulation.

Assemblies and methods for installing visible protective bollards can be expensive, time-consuming, and labor-intensive. On the other hand, assemblies and methods for installing standards T-posts, although cheaper, less time-consuming, and less labor-intensive, are less visible, for example. The present disclosure is directed to bollard cover assemblies, brackets, and methods that overcome the shortcomings of the standard steel protective bollards as well as the standard T-posts. The bollard cover assemblies, bracket, kit, and methods, for example, include a combination of a T-post and one or more brackets, and a bollard cover so that when the cover is positioned over or to surround substantially the combination, the assembly emulates a visible protective bollard.
