<p>A nozzle for a device for machining materials, can be rigidly connected at its end opposite the nozzle tip to a connector head of the device. The connection of the nozzle with the connector head is made by a connecting element (7; 17) made of a brittle material and comprising a break-off region (11; 20). If a collision between the nozzle tip and a workpiece to be machined takes place accidentally, then the connecting element breaks in the break-off region in order to prevent further, even greater damage to the connector head, nozzle or workpiece. The break-off region is crossed by an electrical conductor (14; 27) which breaks in the event of a collision, so that in this way an alarm signal for stopping the device can be generated.</p> |
