Connection device for flat pieces and tubular elements

摘要

The assembly system consists of double (3) and single (4) half collars which are fitted to the tubular components (1) by nuts (6') and bolts (5). Each half-collar has a curved concave recess for a tube, and the bolts are fitted with the aid of pre-positioning bushes (5',6) shaped to engage with the curved surfaces of the tubes or with enlarged holes on the flat components (2).
