A crimping tool and associated method to create a mechanical and electrical connection between two cable elements. A tool body including a first and second attachment points. A first guidance element arranged at a first distance from the first and second attachment points. A second guidance element arranged at a second distance from the first guidance element. The first and second attachment points are arranged on a first side of the first and second guidance elements. A flexible cable with first and second end parts removably attached to the first and second attachment points, respectively. The cable engages the first and second guidance elements. The cable extends between the first and attachment points such that a loop is formed on a second side of the first and second guidance elements. A powering unit configured to increase the first distance so that a diameter of the loop decreases.
