The overvoltage suppressor contains two connecting fittings which are spaced apart from one another along an axis (z) and between which at least o ne cylindrical varistor element is arranged. The connecting fittings and the at least one varistor element 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 with a section which runs essentially transversely with respect to the axis (z), is designe d in the form of a slot and extends from the outer surface of the fitting to beyond t he axis (z). A loop, which absorbs the contact force, is inserted into the sections, which are in the form of slots, in the region of the loop ends beyond the axis (z), an d each of the two loop ends rests on in each case one surface which bounds the section which is in the form of a slot. The overvoltage suppressor is distinguished by goo d mechanical and electrical characteristics and can be produced in a particularly cost- effective manner.
