An extension arm element (6) which can be connected to a vertical column arrangement (1) preferably by gravitational engagement is provided with an attachment member (3, 4) which bears a plug-on member (5) for the connection of the extension arm element (6). Fixedly connected to the extension arm element (6) is a sleeve (7) which surrounds the plug-on member (5) non-positively. The plug-on member (5) is pressed into the sleeve (7) to produce a clamping connection with the extension arm element (6). <IMAGE> |
