Abstract: A training assembly, in particular for vines, the assembly comprising at least two end stakes, a plurality of intermediate metal stakes, supporting crossbars mounted on the intermediate stakes, and moving or fixed support wires extending from one end stake to the other and being supported by the crossbars mounted on the intermediate stakes at heights that are adjusted to be in alignment from one stake to the next. The crossbars are single-piece crossbars, the material of the crossbars is elastically deformable, and the respective profiles of the crossbars and of the intermediate stakes are selected in such a manner as to enable the crossbars to be snap-fastened onto a stake, the crossbar being mounted on a stake by elastically deforming the crossbar by applying external stress thereto, and once the crossbar has been put into position at a selected height on the stake, the crossbar is held to the stake by the elastic return force once the external stress has been released.
