Collision protection device

The invention relates to collision protection device (1) for connecting a welding torch (2) connected to a hose assembly (4) to a robot arm (3) of a welding robot, comprising two coupling elements (6, 7) that can be detachably connected to each other by means of magnets (8), wherein one coupling element (6) is designed to be connected to the welding torch (2) or to a torch coupling (5) that can be connected to the welding torch (2), and the other coupling element (7) is designed to be connected to the robot arm (3), and the coupling elements (6, 7) have openings (10, 11). In order to create a collision protection device (1) having optimal response behavior and to avoid lines extending outside or parts arranged outside, the openings (10, 11) in the coupling elements (6, 7) are designed for feeding the hose assembly (4) through, and the coupling element (6) that can be connected to the welding torch (2) or to the torch coupling (5) or the torch coupling (5) comprises elements (15) to be connected to the hose as
