ABSTRACT A constructional toy is disclosed comprising a plurality of nodal elements and a plurality of co-operating rod elements. Each nodel element is substantially spherical and has a plurality of channels formed upon its peri- pheral surface, including a first channel encircling the nodal element so as to pass through the poles thereof. At least four other channels are spaced about the peripheral surface so as to be intercepted by the first channel adjacent the poles of the nodal element. The lips of each channel have inwardly project- ing beads thereon. Each rod element comprises a shank having a connecting por- tion at each end thereof, the connecting portion including an annular groove and having a longitudinal cross-section of substantially the same configuration as the transverse cross-section of each channel. When a connecting portion of a rod element is 'push-fitted' into a co-operating channel, it is held therein by virtue of the engagement of a lip bead within the annular groove of the connecting portion in such a manner that the longitudinal axis of the rod element is in substantial alignment with the geometrical centre of the nodal element.
