Abstract: A locking arrangement is arranged to lock together a first side and a second side that are at an angle to each other. On the first side, there is a locking member with a bar (6) and a transverse part. On the second side, there is at least one lug (5) and the transverse part (4) is settable to a locked position on the lug (5) on the second side and releasable from the locked position on the lug (5). The lug (5) on the second side is turnable away from beneath the transverse part (4) in the locked position and lockable to remain under the transverse part in the locked position.
