    • A mechanical connection arrangement for panels (1, 2), comprises a first panel (1), a second panel (2) and a mechanical locking device for locking the first panel (1) to the second panel (2). A surface of the first panel (1) and a surface of the second panel (2) are parallel and in contact in a locked position of the first and second panels (1, 2). The mechanical locking device comprises at least one rod-shaped element (3) at said surface of the first panel (1) and at least one corresponding insertion recess (4) at said surface of the second panel (2). The rod-shaped element (3) is configured to be inserted in the insertion recess (4). The lateral surface of the rod-shaped element (3) extends at a first angle (α) from the surface of the first panel (1) and the lateral side of the insertion recess (4) extends into the second panel (2) at a second angle (β) from the surface of the second panel (2). The difference between the first angle (α) and the second angle (β) is between 0.5 and 6, 2 and 4, or about 3 in an unlocked position of the first and second panels (1, 2). The rod-shaped element (3) and the insertion recess (4) are configured such that the difference between the first angle (α) and the second angle (β) is smaller in the locked position compared to when in the unlocked position.

    • A set of panels includes first and second panels 1, 2, and a mechanical locking device for assembly by vertical relative displacement of the panels. A locking strip 7 extends from a first edge 11 of the first panel in a direction parallel to first and second panel surfaces of the first panel. The locking strip includes a locking strip edge, and first and second locking strip surfaces respectively extending in directions substantially corresponding to those of the first and second panel surfaces 12, 13. The locking strip includes a locking element 3 cooperating with a locking groove at a second edge of the second panel for locking in a direction parallel to the first panel surface 12. Opposite edges respectively include cooperating tongue and tongue groove 5, 6 for vertical locking. The first and second edges respectively include first and second engaging positioning elements 18, 28 to decrease vertical movement of the panels in the locked position. Moreover, the set of panels has a thickness Q and comprises a flexing groove arranged with a width T so that the ratio of Q and T is in an interval of 0.05-0.40.
