1. A set of panels, which comprises a first panel and a second panel each comprising a main surface, a first edge, an opposite second edge, a third edge which is adjacent and optionally perpendicular to the first edge, and a fourth edge which is opposite to the third edge, wherein the set comprises a mechanical locking device which is configured to lock the first edge of the first panel to the second edge of the second panel at a joint seam, wherein the locking device comprises a flexible tongue, which is positioned in an insertion groove at the first edge of the first panel and a tongue groove at the second edge of the second panel, wherein the flexible tongue is of an elongated shape and the length direction is parallel to the first edge, wherein the flexible tongue comprises a central part between a first edge part and a second edge part of the flexible tongue, wherein the central part is configured to cooperate with the tongue groove for locking of the first and the second edge in a first direction which is perpendicular to the main surface in a locked position of the first panel and the second panel,
wherein the first edge part and the tongue groove are configured such that when in the locked position a force is applied adjacent the first edge and the third edge of the first panel and another force is applied adjacent the second edge and the third edge of the second panel, the first edge part is pushed towards a bottom surface of the insertion groove which allows a disassembling of the second panel from the first panel by displacing the third edge of the second panel relative the third edge of the first panel.
