A safety protection device for joints, that is knots, of metal scaffolds, especially of a variable geometry type, made up of two caps which are disposed with slight clearance on opposite sides with respect to the center line (a-a) of the joint. Each safety protection device is made up of two bodies each having two facing semicircular recesses so as to delimit, in use, two facing chambers. The chambers are for housing corresponding parts or portions of the joint. Two circular holes are provided for the passage of two tubes connected by the joint. The parts of each one of the caps is connectable to each other in a fixed but removable way. |
