Protective device for a universal shaft as well as protective arrangement with universal shaft and such a protective device

A protective arrangement, comprising:

• a housing with a shaft journal projecting from the housing;
• a universal shaft connected to the shaft journal;
• an attachment element positioned around the shaft journal and being attached to the housing;
• a tubular protective guard extending along a longitudinal axis, the tubular protective guard including a first shell element and a second shell element positioned around the universal shaft, the first and second shell elements connected along respective longitudinal edges;
• and
• a latching device attaching the protective guard to the attachment element;
• wherein the latching device has at least one latching element and at least one latching projection;
• wherein the latching element is arranged on the attachment element and the latching projection is arranged on the protective guard or the latching element is arranged on the protective guard and the latching projection is arranged on the attachment element;
• wherein the latching element is displaceable between a latched position and a release position;
• wherein the latching element is elastically formed and the latching element engages behind the latching projection in the latched position;
• wherein the latching projection has a setting face that interacts, during pushing the protective guard in axial direction onto the attachment element, with the latching element so that the latching element is displaced into the release position;
• and
• wherein a return element is axially supported on the attachment element and on the protective guard and the return element biases the protective guard in a direction away from the attachment element.
