Abstract: A tool for crimping a double connection of a connector to a conductor on one hand and to insulation on the other hand comprises a tool head (1) having a frame (3, 4), a pressing jaw axially stationary on the frame and a pressing jaw axially guided on the frame. A drive (2) is provided for the axially guided pressing jaw, the axially stationary pressing jaw having at least two anvil plates (7, 6) provided with working profiles (24, 25) and the axially guided pressing jaw having at least two associated punch plates (32, 29) provided with working profiles (33). The two cover plates (3, 4), which are spaced apart from one another, form the frame and are provided with parallel aligning surfaces (22) for at least one of the punch plates (32) and at least one at the anvil plates (7).
