Abstract:
The present invention concerns an indication means using the positions of two mutually moveable parts of an element. In one embodiment the indication means is used for a compression wedge of a lead-through system. The wedge comprises a first and a second wedge element (1, 2) moveable towards and away from each other between two extremes. A socket (7) is fastened in a rotatable way to the first wedge element (1) and a screw (6) is fixed to the second wedge element (2). One coloured end (11) of the screw (6) is received in a through opening (17) of the socket (7). The inner surface of said through opening has another colour than the coloured end (11) of the screw (6). The mutual position of the first and second wedge elements (1, 2) are controlled by rotation of the socket (7) on the screw (6).
