A search for non-resonant D(s)+ → π+μ+μ- and D(s)+ → π-μ+μ+ decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb-1, √at s=7TeV recorded by the LHCb experiment in 2011. No signals are observed and the 90% (95%) confidence level (CL) limits on the branching fractions are found to be B(D+ → π+μ+μ-)<7.3(8.3)×10-8, B(Ds+ → π+μ+μ-)<4.1(4.8)×10-7, B(D+ → π-μ+μ+)<2.2(2.5)×10-8, B(Ds+ → π-μ+μ+)<1.2(1.4)×10-7. These limits are the most stringent to date.
