The present invention relates to a surface covering () comprising panels () and at least one extraneous locking element (). The panels () are provided with respective longitudinal and transverse coupling means () which are adapted to connect similar panels () at corresponding adjacent edges (). The transverse coupling means () are adapted to form a channel () in coupled condition which is adapted to receive the extraneous locking element (). When inserted into the channel () formed by the transverse coupling means () of panels () in a first row (), the extraneous locking element is adapted to extend at least partially into the groove () of an adjacent parallel panel in the second row (), such that a lower surface () of the extraneous locking element () is in contact with a lower lip contact portion (), and the upper surface () of the extraneous locking element () is in contact with an upper lip contact portion ().
