Abstract
A connection device for toy construction sets comprises a cylindrical socket and a bolt-like locking element inserted therein. The socket is inserted into the bores of the construction elements to be connected and is provided at one end with a radially protruding outer edge shoulder as a retaining member as well as longitudinal slots. The locking element (9) is rotatable within the socket, but fixed axially and rotation of the locking element causes the socket to lock within the construction element.
