A cable brake includes a pair of brake shoes having braking surfaces facing one another and between which a brake cable is guided. A first brake shoe is movable between a braking position, pressing the cable against the braking surface of the other brake shoe, and a release position, releasing the cable between the brake shoes. A releasable retaining device retains the first brake shoe in the release position, and/or a reset device switches the first brake shoe from the braking position to the release position. Two rotatably mounted pivot arms connected to the first brake shoe are arranged in a parallelogram with one side oriented in parallel with the cable guidance direction. A switchable electromagnet of the retaining device holds the first brake shoe in the release position. The brake shoes, pivot arms, retaining device and reset device are arranged in a housing connected to an elevator car.
