Abstract

A connector for tubular elements, for example scaffolding tubes, comprises at least one cradle comprising two opposed plates, each provided with windows, for the passage of a grip bolt. The cradle is pressed from a blank to form a profile in the form of a basin with a quadrilateral form. Opposed pairs of walls of the basin are then cut to form windows for the passage of the connecting bolts in one direction and openings for the housing of the tubular elements to be gripped in the other direction. The connector is of robust and rigid form with low weight and resistance to slip and of simple manufacture. The elements of the connectors are inseparable and are easily mountable and demountable. In addition the connectors need no maintenance.
