FIELD: machine building. ^ SUBSTANCE: The invention refers to slider couplings. Slider coupling has driving and driven half-couplings with lugs and intermediate floating element with transversely-spaced channels for the corresponding lugs. Intermediate floating element is made in the form of crossbar creating T-form flexible elements. The mentioned flexible elements are made with the base of the crossbar from the pairwise located sides of transversely-spaced channels contacting with half-coupling lugs. ^ EFFECT: invention is aimed at the reduction of dynamic loads transferred through the shafts connected with the coupling. ^ 4 cl, 3 dwg
