1. A mechanical connection arrangement for panels comprising a first panel, a second panel wherein a surface of the first panel and a surface of the second panel are parallel and in contact in a locked position of the first and second panels, the connection arrangement comprising first and second rod-shaped elements at the surface of the first panel and first and second corresponding insertion recesses at the surface of the second panel,
wherein the first rod-shaped element is configured to be inserted in the first insertion recess, and the second rod-shaped element is configured to be inserted in the second insertion recess,
wherein the first and second rod-shaped elements extend at a first angle from the surface of the first panel and the first and second insertion recesses extend into the second panel at a second angle from the surface of the second panel,
wherein both the first and second angles are in the range of about 30° to about 60°,
wherein a difference between the first angle and the second angle is at least 0.5°,
wherein the connection arrangement comprises a locking device which comprises a locking pin at one end and a spring at another end,
wherein the spring is configured to cooperate with a first panel recess in one of the panels and the locking pin is configured to cooperate with a second panel recess in the other panel when the arrangement is in a connected state, and
wherein an end part of the locking pin is cone shaped, an envelope surface of the cone shaped end part comprises a pin locking surface which in the connected state is configured to cooperate with a recess locking surface of the second panel recess,
wherein a lateral surface of the locking pin comprises a radially extending recess, the radially extending recess being a through opening, the radially extending recess having an inner sloping surface configured to be engaged with an unlocking tool.
