Abstract
A connecting device for a toy building set includes two identical connectors, each comprising a primary tubular sleeve having a toothed rim on one end face and a secondary tubular sleeve integral with the surface of the primary sleeve. The secondary sleeve is disposed at right angles to the primary sleeve with one end face adjacent the toothed end face of the primary sleeve. The sleeves have a circular cross-section permitting rotation about a shaft, but rotation is prevented by a pair of stop rings which are frictionally and slidably mounted on the shaft and serve to clamp the sleeves together. When assembled, the two connectors are interlocked by meshing of the toothed rims.
