At least one connecting component has a first connecting part configured for fastening to a pole or surface and an opposite second connecting part having at least one male coupling element and at least one female coupling element for engaging and locking with mating coupling elements of another connecting component. The male and female coupling elements on opposing connecting components are engaged to interlock.
