A connector for butt-connecting two chipboard components having two connector parts, which, mutually rotated through 90°, can be pushed together, into one another, into a locked assembly position and are in the form of U-shaped brackets having two outer bracket arms, which respectively have a rear plug-in portion for insertion into a circular drill hole of one component and an expandable front plug-in portion, forming the free bracket end, for insertion into a circular drill hole of the other component. A middle bracket arm is for expansion of the two front plug-in portions of the respectively other bracket in the assembly position. At least one locking portion for the mutual locking of the two brackets in the assembly position is provided. The outer sides of the rear plug-in portions are each configured, at least approximately, as partial lateral surfaces of the same circular cylinder.

Panels are shown which are provided with a mechanical locking system allowing perpendicular connection with a snap action. A set of panels including a first and a second panel, an edge of the second panel is insertable into a groove of the first panel, when the panels are arranged essential perpendicular to each other, to obtain a mechanical connection between the first and the second panel, when the second panel is displaced essentially perpendicularly to the first panel.
