1. A panel comprising:

  • a body with at least one plastic layer,complementary locking means provided in pairs at mutually opposite panel edges,at least one pair of locking means with hook profiles, namely a receiving hook and in opposite relationship thereto an arresting hook,the receiving hook has, remote from the body, a hook edge and arranged nearer to the body a receiving recess, wherein the receiving recess is open towards a top side of the panel, the arresting hook has an arresting recess arranged nearer to the body and open to an underside of the panel and has an arresting step which is arranged remote from the body and which fits in a vertical joining direction into the receiving recess of the receiving hook,the arresting hook has a joining surface remote from the body and also remote from the body a vertically acting arresting contour,the receiving hook has a joining surface nearer to the body and also nearer to the body a positively locking contour which fits together in positively locking relationship with the arresting contour, that is remote from the body, of the arresting hook so that vertical locking can be implemented,the arresting hook has arranged nearer to the body a horizontal locking surface at the arresting step,the receiving hook, arranged remote from the body, has a horizontal locking surface in the receiving recess,a narrowed receiving opening is formed at the receiving hook through which the arresting step can be inserted substantially in the vertical joining direction into the receiving recess,a free step end of the arresting step is narrower than the width of the receiving opening of the receiving hook,the arresting contour, that is remote from the body, of the arresting hook is set back behind the plane of the joining surface of the arresting hook,the positively locking contour, that is nearer to the body, of the receiving hook projects at least partially beyond the plane of the joining surface of the receiving hook,the arresting step and the receiving opening are of a configuration that the free step end during a joining movement initially fits without elastic deformation of the hook profile into the receiving opening to such an extent that a part of the horizontal locking surface of the arresting hook makes contact with the horizontal locking surface of the receiving hook and the receiving hook has a flexural leg so adapted that the width of the receiving opening can be enlarged by elastic bendability of the flexural leg so that the arresting step can be entirely inserted into the receiving recess and also the arresting contour of the arresting hook is inserted into the positively locking contour of the receiving hook, wherein a bottom surface of the flexural leg is in a common plane with a bottom surface of the body.
