Abstract
An improved connector element is disclosed, for use in toy construction sets. The connector is of injection molded construction, using a minimum weight of plastic material and designed for high speed, high volume production as extremely low cost. The connector includes lugs arranged to be received within tubular structural elements, for example plastic straws. The lugs have a full-length, longitudinal slot recess defining opposed lug portions normally slightly larger at the outer and inner end extremities than the interior of the structural elements. The slot recess is wider in the center portions then at either end. An integral compression post extends between the opposed lug portions in the region of the wider portions of the slot recess, so that only the outer portions of the lugs deflect inwardly when inserted into a tubular structural element. The body of the connector is formed of a central tubular hub surrounded by a thin walled flange which mounts the lugs. A thin web connects the tubular hub and the flange. Because of its low cost, it is practical to use the devices in large numbers in construction toy sets.
