摘要：A fastener (110) includes a head (112) having a through passage (114), acomposite, double legged shank (118, 118.1, 118.2), and a pulling element (120)extending from a free end of the shank, between the legs and through the head via thepassage. The pulling element has a small head (121) abutting the free end of the shank.Along one side of pulling element it has serrations (120.1) complemental to serrations(114.1) along a corresponding side of the passage to allow relative displacement

between the pulling element and the head in one direction only. The assembled fastener(110) is passed through holes (23) in layers (22, 24) to be interconnected. With the headabutting the layer (24), the pulling element is pulled to dilate the legs (118.1, 118.2)under compression to abut the layer (22). The pulling element is anchored on the headby means of the serrations to keep the shank in dilated condition.
