1. A lock for a motor vehicle, the lock comprising:
an actuating lever chain having at least one actuating lever, wherein the actuating lever is configured to unblock a locking mechanism of the motor vehicle from a blocked position;
a mass inertia element mounted in the lock; and
a plastics mandrel mounted in the lock, wherein the plastic mandrel includes an arm extending outward from the plastics mandrel which interacts with a recess in the mass inertia element and a joining face, wherein the arm and the joining face are arranged for sandwiching the mass inertia element between the joining face and the arm when the mass inertia element is attached to the plastics mandrel, wherein the mass inertia element is mounted in the lock by the plastics mandrel, wherein the joining face is configured so that a spring preload is introduced into the mass inertia element toward the arm to press the mass inertia element into direct contact with the arm,
wherein the joining face has a planar surface,
wherein the plastics mandrel further includes a plurality of flexible tabs molded into the joining face that protrude beyond the planar surface of the joining face, when the mass inertia element is not mounted on the plastics mandrel, and
wherein the flexible tabs each includes a spherical surface that is configured to provide the spring preload into the mass inertia element.
