A device for locking two building boards connected to one another, in particular flooring panels with a core of wood material or wood material/plastic mixture, in a direction (V) perpendicular to a visible side. The device includes a first building board with a lateral edge (I) and a first groove provided in the core of the building board and running parallel to the visible side. The device further includes at least one second building board with a lateral edge (II) and with a second groove provided in the core of the building board and running parallel to the visible side, and a locking element that is placed in the first groove of the first building board in order to engage in the second groove of the second building board, when both grooves have reached an overlapping position after the connection of the building boards by a vertical lowering movement. To lock the two building boards in a direction (H) parallel to the visible side, on one of the lateral edges (I), a lower lip projecting beyond this laterally with an outer projection projecting upwards is provided. On the lateral edge (II) lying opposite this lateral edge (I) a recess is provided directed towards an underside, which recess is embodied in a manner corresponding to the projection. The locking element can be bent out in the transverse direction (H) by forces acting thereon in the longitudinal direction. The locking element has at least one projection facing the groove base, which projection engages in a recess provided in the groove and projects into the core and can thus be locked in place based on the longitudinal direction (L).
