A portable scaffold having tubular structural elements has necked fittings extending into the ends of the tubular elements and attached thereto by adhesive which is introduced through an entry port preferably provided by a porting ring sleeved on the neck of each fitting and opposed by an O-ring. The adhesive flows from the entry port through longitudinal and circumferential grooves in the neck between the porting ring and O-ring and vents through a vent port in the porting ring.
