| Abstract |
A Clamping unit for a functional element more particularly suitable for demonstration and/or training purposes, which is releasably mounted on the mounting surface of a supporting member (i). It has a clamping means (8) which is able to be introduced into an attachment recess (3) in the supporting member (1) and which is operated by turning an actuating element (12). A downwardly projecting clamping head (18) is arranged on the actuating element, which is able to be introduced into the attachment recess (3) and may be so positioned by rotation that it fits behind two holding projections in the attachment recess (3). By further rotation of the actuating element the functional element is clamped against the surface of the supporting member (1) . |
