A modular climbing tree comprises at least a plurality of poles (34) and connecting components (1213641) configured for connecting the poles (34) or for connecting poles (40) and accessories. The connecting components (1213641) comprises at least one connecting component (1213641) that has a first connecting part (3233742) configured for fastening to a pole (34) or a surface and an opposite second connecting part (422443) having at least one male coupling element (5a,5b) and at least one female coupling element (6a,6b) for engaging and locking with mating coupling elements (6a,6b5a,5b) of another connecting component (1213641) selected from the connecting components (1213641). The at least one male coupling elements (5a,5b) and at least one female coupling elements (6a,6b) on opposing connecting component (1213641) are engaged to interlock. Thereafter the opposite connecting component (1213641) are rotated about their common axis to further lock together in detachable manner.
