Improvements introduced in the manufacture of protective insulating tubes for electrical installations consisting essentially of forming the joining of the edges of the metallic covering strip of said tubes by folding said edges together and subjecting the edges once bent to a compression by means of rollers provided with hollows or reliefs so that the two sheets forming the closure are embedded and embedded one another in the points corresponding to the projections of the pressure roller leaving both sheets firmly crimped ensuring that they can not be separated or eventually separated.
