Astrophys.// **566**, (2014) Art. No. L6.\\ The 1<sub>11</sub> – 0<sub>00</sub> transitions of H<sub>2</sub><sup>35</sup>Cl<sup>+</sup> and H<sub>2</sub><sup>37</sup>Cl<sup>+</sup> were observed with ALMA redshifted from about 485 GHz to about 257 GHz. The <sup>35</sup>Cl/<sup>37</sup>Cl isotopic ratio agrees within error bars with the terrestrial ratio.\\ \\ S. H. J. Wallström, S. Muller, E. Roueff, R. Le Gal, J. H. Black, and M.
