Abstract
A pressing tool for coupling elements includes a forked receiver, a clamping claw which is interchangeably held in the receiver by a connecting pin, and a drive motor for the activation of the clamping claw. The connecting pin can be inserted through holes bored in the forked receiver and the clamping claw crosswise relative to the lengthwise direction of the housing of the pressing tool. A monitoring element is provided, which checks to ensure that the connecting pin is fully inserted. The monitoring element is connected to the power source of the drive motor by means of a switching element.
