In this paper, investigation of tensile testing for specific assemblies of two elements, jointed by mechanical fasteners, are presented. One element is a specific small diameter tube. This element is produced by filament winding technology using glass fiber impregnated with polyester resin. Another element is cylindrical steel part, obtained by standard technology. Basic data about composite materials and mechanical fastening are presented. Pins and rings were used as mechanical fasteners. Data of tubes preparation and assembling glass fiber/polyester resin tubes and cylinder with pins and rings are presented. The assemblies specific composite material parts/metallic parts jointed by fasteners were exposed to the action of axial tensile stress. A tensile breaking force of the assemblies was determined and the influence of pins number to tensile breaking force was presented. A failure mechanism of specific composite tubes fastened with pins and rings is described
