Abstract
A panel, particularly a floor panel, which exhibits a spring on at least one side and a groove on the opposite side, which features are designed in complementary fashion such that several panels can be connected by inserting one panel into the other, while the spring/groove connection is provided with interlocking portions which prevent the two panels from sliding against the connecting direction, is distinguished by the fact that the spring exhibits a slit that runs parallel to the upper side of the panel and the groove exhibits a wedge-shaped projection at its base.
