A clutch which reacts to torque overload has a ribbed disc which is produced by plastics injection moulding and which is, along its inner or outer periphery, encapsulated in encircling fashion and on both axial side surfaces by an encompassing ring. Said encompassing ring, owing to shrinkage as a result of cooling, enters into static friction engagement with the ribbed disc, and furthermore engages, by means of bevelled flanks, with ribs running radially on at least one of the side surfaces of the ribbed disc.
