ABSTRACT OF THE DISCLOSURE An easy-to-build, hinged, three-dimensional display system is primarily intended for advertising and display purposes, built of bars or tubes and connecting pieces. The bars or tubes are pivoted to each other in pairs at their mid points and form crossing diagonal struts in the display system. Each pair of diagonal bars or tubes is either on a mutually parallel, horizontal plane or on a vertical plane that is at right angles to the former. The system is braced vertically by easily mountable and dismountable struts, preferably in the form of rails which are attached on the outside of the display system on and between adjacent connecting pieces and on the outward-facing side of which pictures, illustrative material, etc., can be attached. Each connecting piece includes a central part, and one end of the central part is equipped, in an offset, tetraskelian configuration, with four tangentially protruding pivot pins, which are shifted 90° in relation to each other and which are designed to be inserted in holes arranged transversely through the ends of the tubes or bars, whereby the length of the pivot pins somewhat exceeds the thickness of the tubes or the bars and the bars or tubes can be locked to the pivot pins by means of easily insertable locking devices, preferably in the form of spring washers. The other end of the central part is equipped with quick-coupling devices for the fastening of the vertical struts.
