本发明涉及一种旋转闭合两个板状部件的可拆卸的连接（1，2，3），每个具有通孔，其中一个所述通孔（3b）中不是旋转对称的。 旋转封闭件具有具有第一抵靠表面的封闭元件（10）（11），第二接触面（12），以及围绕彼此两个接触表面的旋转轴线（14）枢转连接销（13）（11，12）， 间隔开地连接并且与第一支承表面（11）和第二支承表面（12）在中心处连接，其中抵接表面（11,12）从旋转轴线径向突出。 旋转盖还具有带导向通道（21）的导向元件（20），连接销（13）可旋转地安装在导向元件（20）中。 一个支承表面（11，12）可从组装位置枢转到锁定位置，其中，所述抵接表面（11，12）的包络在装配位置内的从所述非旋转对称的通孔（3b）中所描述，位于锁定位置的包络线的外侧 ， 在封闭元件（10）和/或引导元件（20）上可形成接合在凹部（27）中的突出部（18）。

The invention relates to a rotary closure for the detachable connection of two plate-shaped components (1, 2, 3) each having a through hole, one of said through holes (3b) is not rotationally symmetrical. The rotary closure has a closure element (10) having a first abutment surface (11), a second contact surface (12), and around a rotation axis (14) pivotally connecting pin (13) of the two contact surfaces (11, 12) from each other, spaced to one another and centrally with the first and second abutment surface (11, 12) is connected, wherein the bearing surfaces (11, 12) radially projecting from the rotation axis. The rotary closure additionally comprises a guide element (20) with a guide channel (21) in which the connecting pin (13) is rotatably mounted. One of the bearing surfaces (11, 12) can be pivoted from an assembly position into a locking position, wherein the abutment surface (11, 12) envelope described in the assembly position within a from the non-rotationally symmetrical through-hole (3b) and is located in the lock position outside of the envelope , On the closure member (10) and / or the guide element (20) may be formed a protrusion (18) which engages in a recess (27).
