Title: Joint

Abstract: A joint for two flat structural members, in particular floor panels, wherein a groove and tongue joint joining the two flat structural members is provided functionally separate from a twistlock locking the two flat structural members. The twistlock is formed on one of the structural members, the is spaced apart from the groove and tongue joint, and engages with a correspondingly formed engaging element of the other structural member. The locking is preferably formed both at the longitudinal edges and at the front edges of a rectangular structural member, such as a floor panel. The locking allows for a joint of the floor panels to occur in flat position, i.e. without twisting.
