The invention relates to a panel (1, 2, 27, 28) comprising a body (1', 2') having at least one plastic layer, complementary locking means (V) provided in pairs on opposite panel edges, at least one pair of locking means having hook profiles (H), namely a receiving hook (5) and a locking hook opposite thereto, wherein the receiving hook (5) comprises a hook edge (8) disposed away from the body and a receiving recess (9) disposed near the body, wherein the receiving recess (9) is open to the top side (7), wherein the locking hook (6) has a locking recess (11) disposed near the body and open to the bottom side and comprises a locking step (12) disposed away from the body and fitting in the receiving recess (9) of the receiving hook (5) in the vertical joining direction, wherein the locking hook (6) comprises a joint surface (13) away from the body and a vertically active locking contour (14) also away from the body, wherein the receiving hook (5) comprises a joint surface (15) closer to the body and a form-fit contour (16) also closer to the body and fitting together with the locking contour (14) away from the body of the locking hood (6) in a form-fit manner, so that a vertical locking can be brought about, wherein the locking hook (6) comprises a horizontal locking surface (17) disposed closer to the body on the locking step (12) thereof, wherein the receiving hook (5) comprises a horizontal locking surface (18) disposed away from the body in the receiving recess (9), wherein a narrowed receiving opening (19) is formed on the receiving hook (5), through which the locking step (12) can be inserted into the receiving recess (9) substantially in the vertical joint direction (T), wherein the free step end of the locking step (12) is designed narrower than the width of the receiving opening (19) of the receiving hook (5), wherein the locking contour (14) away from the body of the locking hook (6) is short of the plane of the joint surface (13) of the locking hook (6), wherein the form-fit contour (16) closer to the body of the receiving hook (5) protrudes at least partially past the plane of the joint surface (15) of the receiving hook (5), wherein the locking step (12) and the receiving opening (19) are designed so that the step end fits into the receiving opening (19) far enough at first that a part of the horizontal locking surface (17) of the locking hook (6) makes contact with the horizontal locking surface (18) of the receiving hook (5) during a joining motion without elastic deformation of the hook profiles (H), and that the receiving hook (5) comprises a bending bar (20) implemented so that the width of the receiving opening (19) can be expanded by the elastic flexibility thereof, so that the locking step (12) can be inserted entirely into the receiving recess (9) and the locking contour (14) of the locking hook (6) is further inserted into the form-fit contour (16) of the receiving hook (5). |
