An adaptor comprising an outer screwed sleeve member and a lining press member is provided for the connection of two hollow tubes. A slidable threading lug is fitted over each of the hollow tubes. By fitting the hollow tubes one over the other, the net posts of the present invention can be reduced in dimensions to facilitate storage, shipment and carrying and can also facilitate adjustment and operation. Moreover, the installation of the net posts and the height adjustment of the net for use are facilitated by the provision of the threading lugs.
