Definitions

• the invention relates to a pipe mounting system for empty and light pipes for the construction of exhibition stands and shops and their equipment with shelves, tables, seating, cupboards, advertising media, lighting systems, coat racks, railings and the like, in which the ends of two pipes by a spreadable Plug insert are releasably connectable, the plug insert being formed from two half-shells made of plastic which enclose the tubes profiled on the inside and form an outer ring between the tube ends and are arranged in such a way that they cannot rotate and are expandable by a screw accessible from a half-shell outer ring.
• the object of the invention is to improve a pipe mounting system constructed according to the type mentioned at the outset in a simple manner with regard to the connection strength of the pipes and to fix the pipes in a stable manner in all circumferential directions.
• the pipe mounting system according to the invention works with three or four core parts and with one or two wedges, which spread the core parts radially outwards in all circumferential directions of the pipes, so that a large-area, practically over the entire pipe circumference is achieved and thus the pipes are securely fixed and held together in all directions.
• the pipes Due to the bracing on the entire circumference, the pipes can have smaller wall thicknesses and the core parts with the wedges are also of smaller volume compared to the known design, which makes the entire pipe assembly system lighter in weight and yet very stable; this Points represent a further object solution of the invention with regard to stability and weight training.
• the tubes and the calf shells have a tongue and groove profile in an advantageous, equally large circumferential angle distribution, which enables the tubes to be axially adjusted relative to one another in favorable angular ranges and at the same time results in a good anti-twist protection between half-shells and tubes.
