<p>The invention relates to a connecting device for connecting of a ring-shaped frame (1) , which is adapted for fixation to the head of a patient during neurological diagnosis, therapy or surgery, to a supplementary equipment (5) , for positioning of the frame and the equipment in a predetermined relation to each other. The frame comprises a connecting hole (6) and the equipment comprises a connecting pin (11, 12) for insertion into the hole in the frame during positioning. The hole (6) opens into a surface of the frame (1) and has an enlarged portion (9) , which preferably is diverging towards the surface of the frame, closest to the surface and a cylindrical portion (10) beyond the diverging portion, whereas the connecting pin has a cross sectional dimension which is equal to or slightly smaller than the cross sectional dimension of the cylindrical portion in the hole .</p> |
