1. A channel fastener for fastening an object to an elongate channel element having a longitudinal slot defined between flanges,
wherein the channel fastener comprises:
a rigid washer element, having a bearing face;
an oblong metal anchoring element having a width and a length, wherein the width is smaller than the length, said anchoring element being located on the side of the washer element where the bearing face is located and having longitudinal end portions;
a connecting element which connects the anchoring element to the washer element, while allowing the anchoring element to rotate with respect to the washer element, wherein-after a rotation of the anchoring element, the anchoring element is in a locking position; and
a torque-inducing element fixed to the anchoring element, the torque-inducing element including at least one resiliently deformable limb arranged substantially offset from a rotational axis of the anchoring element, wherein the at least one resiliently deformable limb in an initial state extends from the anchoring element towards the washer element, wherein the resiliently deformable limb has a proximal end located at the anchoring element and a distal end located against the washer element, and wherein the resiliently deformable limb is adapted for a sliding engagement with at least one of the flanges of the channel element, such that said limb is configured to deform as it passes the flange, by which deformation a torque on the anchoring element is induced, so as to rotate the anchoring element towards the locking position.
