The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform and single movement as opposed to currently available products. The securing device has two handles pivotably connected and a gripping means moveably associated with one handle. As the handles are activated and the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place.
