Abstract: A device for removing formlockingly anchored dowels including an anchor rod and an expansion sleeve (31) displaceable along the anchor rod, the device including a sleeve-shaped support member (2) having, at one of its ends, a support shoulder, an indexing projection (4) extending beyond the support shoulder (3) and provided with a load application element (5) movable in a tensile operational engagement with the load application element (32) of the dowel sleeve (31); and a through-bore provided with an inner thread for receiving a shaft (7) having an outer thread (8) cooperating with the inner thread of the through-bore (6) to provide for a relative axial displacement of the shaft (7) with respect tot he support member upon rotation of the shaft (7), the shaft (7) having identical coupling elements (11) provided at its opposite longitudinal ends, and an adaptor (12) including an elongate section (13) having at its free end connection element (14) corresponding to the coupling element (11) of the shaft (7) and

Abstract: A dowel including an anchor rod (2) provided at front, in a setting direction, end with a head portion (4) widening in the setting direction, and a sleeve (5) having a through-bore and axially displaceable along the anchor rod, with the sleeve (5) having, at its end adjacent to the head portion (4) an expansion region (6) formed by a plurality of expansion tabs (7) separated from each other by substantially axially extending slots (8) and radially expandable upon a relative displacement of the sleeve (5) and the anchor rod (2), and a sleeve section adjoining the expansion region (6) and having, in its rear end region (10), a larger diameter (G) than in its front end region (12) adjoining the expansion region (6), with the sleeve section having a narrowing intermediate region (11) extending between the rear end region (10) and the front end region (12) and having a smallest outer diameter (M) which is smaller than an outer diameter (F) in the front end region (12).
