The dowel (4) has an internal hole (9) with longitudinal ribs (10) for screwing an attachment screw into, and has a flange (5) with a filling opening (7). The dowel (4) has a plurality of flange-like blocking elements (3), which run transversely with respect to the longitudinal axis, for fixing the dowel in the drilled hole (2). The locking elements (3) are provided with perforations (8) in the axial direction and have a profile which tapers in the form of a wedge towards the wall of the drilled hole. The remaining cavity in the drilled hole (2) is filled with a curable binding agent by means of an injection device (6) which is attached to the filling opening. The device is particularly suitable for building blocks having cavities or for porous building materials and can also be used in conjunction with wood screws. <IMAGE> |
