Abstract: A connector is disclosed which is useful as an element of a toy construction set, or in constructing various structures which can be easily disassembled. The connector includes a mutual connection portion for use in mutually connecting a plurality of connectors and which includes a female connecting portion formed by a recess with an octagonal inner cross section and a male connecting portions formed by a projection with an octagonal outer cross section. A clip member is preferably unitarily formed with the mutual connection portion and extends away therefrom for gripping a planar object and securing the planar object relative to the mutual connection portion. The clip member includes a pair of substantially parallel horizontally elongated legs fixed to the mutual connection portion and extending therefrom. The elongated legs are resilient and closely adjacent one another, such that they are adapted to grip the planar object by way of a biasing force.
