is presumed that the flooring is desired to be separated along a dotted line a in order to release a portion thereof for removal or for remounting at some other edge area of the flooring and it is illustrated that the disconnection may be effected by a bending up of the edges of the flag members 1 either at one side 1a or at the other side 1b of the line a principally it would be sufficient to effect a bending of the flag members 1 at only one side of the line a but since a downward bending is not possible when the flooring is supported on a rigid floor a corresponding effect is obtained by bending upwardly the edge of the adjoining flag member 1 at the other side of the line a the flag members 1 are principally identically shaped one of them being illustrated in more detail in fig2 5 the flag member is a die cast plastic member comprising a top plate portion 2 having along its outer edge a depending edge flange 4 provided with a protrusion 6 near each corner to the right thereof spaced similarly from the corner to the left thereof the edge flange 4 is shaped with a vertical slot 8 opening towards an interior recess as described below the top plate portion 2 is provided with a plurality.
