Abstract: The invention relates to a cable clamp for clamping cables to the cross rungs of a cable ladder, each cross rung being an elongate element having a `top` cross-section. The cable clamp includes a U-shaped bracket having a saddle element displaceable relative to the bracket between the limbs thereof, the free ends of the limbs having slot formations therein whereby the bracket can engage one flange or edge region of the cross rung so that with the cable passing between the limbs of the bracket, the saddle element can be displaced towards the cross rung to clamp the cable between the cross rung and the saddle element.
