Abstract
A toy construction set connection device consists of a shaft and a shaft bushing. The bushing consists of two bushing parts which are fixedly mountable on the shaft. By means of an axial or rotational displacement of the second bushing part relative to the first bushing part, the whole shaft bushing can be anchored in a desired transverse groove on shaft. The anchoring may be released by pulling the second bushing part from the first part.
