ABSTRACT:
A connection system for connecting struts formed from paper or paper-like sheets rolled into a tube is made of cylindrical receptors and connectors. Each cylindrical receptor has an inside diameter approximately equal to or slightly smaller than the predetermined outside diameter of the tube for friction-fit engagement onto the end of the tube. Each cylindrical receptor also has a finger which is centrally disposed within the receptor, about the longitudinal axis thereof. At least a part of such finger is substantially the same size as the inside diameter of the tube. The finger is made of a plurality of longitudinal ribs extending radially from its longitudinal axis. Each receptor is press-fit engageable with a connector. Each connector is press-fit engageable with at least two receptors. The connection system allows for the connection of struts which can be readily constructed by the user of the construction system.
