A coupling sleeve for tubes or bars of rond cross-section has two circular bores at right angles to each other, in two planes above each other, with holding screws. To secure tubes or bars in the longitudinal direction, bores are arranged centrally in the end faces. These continue a little. under the bottom edge of the respective cross bores. Diametral slots at both ends continue to the same depth. This creates a universal coupling for use in laboratories for joints of bars, tubes and plates. |
