Front unit of a touring ski binding with a mounting arrangement for crampons

A fastening assembly for a crampon that is to be coupled to a ski, the fastening assembly comprising:

• at least one mounting fastening portion, wherein the at least one mounting fastening portion defines:
• a first gap which extends in a direction extending substantially transversely to a ski longitudinal direction and so as to be substantially in parallel with a ski surface, and which is configured for receiving a mounting portion of a hinge pin of a crampon, and
• a first opening which extends in the direction extending substantially transversely to the ski longitudinal direction and so as to be substantially in parallel with the ski surface, and which is configured for insertion of the mounting portion of the hinge pin through the first opening, wherein a dimension of the first opening in the ski longitudinal direction is larger than a dimension of the mounting portion of the hinge pin in a first direction orthogonal to a longitudinal direction of the hinge pin, and smaller than the dimension of the mounting portion of the hinge pin in a second direction orthogonal to the longitudinal direction of the hinge pin;
• and
• at least one securing fastening portion, wherein the at least one securing fastening portion defines:
• a second gap which extends in the direction extending substantially transversely to the ski longitudinal direction and so as to be substantially in parallel with the ski surface, and which is intended for receiving a securing portion of the hinge pin, and
• a second opening which extends in the direction extending substantially transversely to the ski longitudinal direction and so as to be substantially in parallel with the ski surface, and which is configured for insertion of the securing portion of the hinge pin through the second opening, wherein the at least one securing fastening portion is resiliently yielding at least in part, and wherein a dimension of the second opening in the ski longitudinal direction is smaller than a dimension of the securing portion of the hinge pin.
