Abstract
An anchor dowel assembly includes an axially elongated sleeve with window-like openings extending through its wall transversely of the axial direction. Locking members are positionable within the window-like openings for displacement radially outwardly from the sleeve for effecting the anchoring action. The locking members are displaced radially outwardly by an expansion tool driven between the locking members by a force directed in the axial direction of the sleeves.
