摘要： A dowel including an anchor rod (2; 22) having a load application element at one of its longitudinal ends and a head (3; 23), a diameter of which increases toward the free end of the anchor rod, at its opposite end, an expansion sleeve (4; 24) having a bore through which the anchor rod (2; 22) extends and a plurality of expansion tabs (5; 25) separated from each other by longitudinal slots (6; 26) and extending from a circumferential groove (7) toward the head (3; 23), the expansion tabs (5; 25) expanding radially, upon the expansion sleeve (4; 24) being displaced over the head (3; 23), and a substantially ring-shaped member (8; 28) arranged in the circumferential groove (7) and substantially filling out the circumferential groove (7; 27) in an expanded condition of the expansion tabs (5; 25).
