Abstract: A connecting device (1) for the shear-force connection of concrete components (20), in particular prefabricated concrete components, comprises: an elongate protective box (2) for fitting in an end face (20?) of the components (20), which comprises a bottom (5) and at least two side walls (6) extending in a longitudinal direction of the bottom; at least one flexible reinforcing loop element (3) which can be accommodated in the protective box (2) and can be moved out of the latter; characterized in that the bottom (5) has a bottom profiling with groups of bottom projections (7) and bottom depressions (7?) alternating in the longitudinal direction, wherein each group has at least one bottom projection (7) or at least one bottom depression (7?).

Abstract: A device for attaching and lifting concrete parts, in particular reinforced concrete prefabricated elements, having a storage box and at least one flexible rope element which penetrates the storage box and has a rope loop and an end anchor, with the rope loop being at least partially accomodatable in the storage box and releasable thereform. At least one of the rope loop and the end anchor of the at least one flexible rope element assumes, at least in sections, an angle of between 0 and 45° to the bottom of the storage box.
