The overvoltage suppressor contains two connecting fittings (1, 2), which are spaced apart from one another along an axis (z) and between which at least one cylindrical varistor element (8) is arranged. The connecting fittings (1, 2) and the at least one varistor element (8) are braced with respect to one another, forming a contact force, to form a mechanically robust active part of the overvoltage suppressor. The active part is sheathed by a molded housing made of insulating material. In each case one material cutout is formed in each of the two connecting fittings (1, 2) with a section (15, 16) which runs essentially transversely with respect to the axis (z), is designed in the form of a slot and extends from the outer surface of the fitting (1, 2) to beyond the axis (z). A loop (5), which absorbs the contact force, is inserted into the sections (15, 16), which are in the form of slots, in the region of the loop ends beyond the axis (z), and each of the two loop ends rests on in each case one surface (17, 18) which bounds the section (15, 16) which is in the form of a slot. The overvoltage suppressor is distinguished by good mechanical and electrical characteristics and can be produced in a particularly cost-effective manner.
