    This invention relates to personal protective equipment. The purpose of the invention is to increase the degree of tightness while improving the usability of the device. The device for mounting a respirator on a protective helmet contains two lateral connecting levers 5, each of which is made of two elements 6, 7, mounted slidably relative to each other and connected to an internal spiral spring compressed by these elements, pushing them into one another. One of the elements 7 is pivotally connected by a foot 8 to the side of the respirator, and the other element 6 is provided at the rear end with a foot 13 interacting with a gripping groove located on the side of the helmet head. One end of the spring 15 is connected to the support surface of the element 7. The device is provided with a rod 16 movable in the longitudinal direction of the lever 5, made with a flange 19. The lever 5 has a stop block 21 of the rolling rod 16 in any position corresponding to the predetermined compression of the spring 15, and releasing it . While the other end of the spring 15 is fixed on the flange 19 of the rod 16. 9 Cp f-ly, 6 ill.
