1. A set comprising a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, wherein:
the first panel comprises a first edge surface and a first panel surface,
the second panel comprises a second panel surface,
the first edge surface is facing or parallel to the second panel surface in a locked position of the first and the second panel,
the mechanical locking device comprises at least one rod-shaped element at the first edge surface and adjacent a front edge of the first panel, and at least one insertion groove at the second panel surface,
the rod-shaped element is configured to cooperate with the insertion groove in the locked position,
the rod-shaped element extends at a first angle from the first edge surface,
the insertion groove extends into the second panel surface at a second angle from the second panel surface,
the mechanical locking device further comprises a locking groove at the second panel surface and a locking part at the first edge surface and adjacent a back edge of the first panel,
the rod-shaped element is positioned between the locking part and the front edge,
the locking groove comprises at least one locking surface extending at a third angle from the second panel surface,
the locking part is configured to cooperate with the locking groove and lock against the locking surface in the locked position,
the third angle is different than the first angle, the first angle is within the range of about 30° to 60°,
the locking part is arranged in a locking part groove on the first edge surface, wherein the locking part is configured to resiliently retract into the locking part groove and is biased to extend in a direction away from a bottom surface of the locking part groove, and
the first and second panels are configured to become locked by displacing the first panel relative to the second panel surface in an assembly direction which is essentially parallel with the first angle, during which time the rod-shaped element slides into the insertion groove and the locking part resiliently retracts at least partially into the locking part groove via contact between an end surface of the locking part and the second panel surface, at least until the locking part springs into the locking groove such that, in the locked position of the first and second panels, the locking part extends into the locking groove.
