The invention relates to a surge arrester having at least one varistor block 1; two end fittings 3; one reinforcing element 9 which holds the varistor block 1 under tension at the end fittings 3 and at least one anchoring element 13, which holds the reinforcing element 9 in a hole 11 through at least one of the end fittings 3. The reinforcing element 13 is preferable a wedge which splits the reinforcing element 9 and braces with the outer walls of the through-hole 11. Alternatively, two or more glass-fibre-reinforced reinforcing elements are held in a through-hole 11, and a wedge between these reinforcing elements ensures that the reinforcing elements are held with a force fit in the end fitting in the area of the through-hole 11.
