The invention refers to the agricultural machinery, namely to devices for solution treatment of the field crops, and may be used for production of broadcast booms of the field sprayers.The spray boom contains a central section, lateral intermediate and lateral marginal sections, placed on both sides thereof, articulately connected thereto, each of which includes supports, contiguously placed in the working position, as well as a device for fixation of each pair of intermediate and marginal sections. Novelty of the invention consists in that on both sides of the support of each lateral marginal section there are rigidly placed fixing plates, between which it is placed the support of the lateral intermediate section, at the same time onto the support it is fixed the body of the fixation device, inside which it is freely placed, perpendicular to the support, a spring-loaded slider, the free end of which is made L-shaped bent and fixed to the support of the marginal section.
