Length of stop screw is not less than diameter of cross-section of sections and extent of spring is determined by distance from stop screw to end of joining rod on side remote from point of joining of sections. Head-gripper has shape of extended body placed for orientation in working position in parallel to longitudinal axes of screws. In addition fastener can have several stop screws arranged along extended body. EFFECT: simplified design of fastener with preservation of reliability and reduced number of parts included in it. 1 cl, 2 dwg
