ABSTRACT:
An improved joint for a bicycle frame has a first sleeve for receiving a head tube and a second sleeve projecting laterally from the first sleeve, for receiving a top tube or a downtube, wherein the second sleeve includes an inner tube and an outer tube, which coaxially project from the first sleeve and which are spaced from each other with a circumferential clearance which is slightly larger than the thickness of the top tube or the downtube so that the top tube or downtube may be snap fit into this clearance.
