A high-statistic data sample of Ar(1.76 AGeV)+KCl events recorded with HADES is used to search for a hypertriton signal. An upper production limit per centrality-triggered event of 1.04x10(-3) on the 3 sigma level is derived. Comparing this value with the number of successfully reconstructed. hyperons allows to determine an upper limit on the ratio N-A3H/N-A, which is confronted with statistical and coalescence-type model calculations.
