The invention relates to a pneumatic cold riveting installation, applicable to industrial assembling with steel rivets having the maximum diameter of 5 ... 6 mm or with reduced hardness rivets made of non-ferrous metals. According to the invention, the installation comprises a pneumatic motor (A) and a lifting-lowering mechanism (B) consisting of a metallic frame (14) linked to some guides (15, 16, 20) to levers (17, 18, 19) which drive a return spring (24) and a locking screw (21). The installation is controlled by means of a double-pedal device (C), which comprises a nozzle of a duct (10) provided with a tap (11), a lower step of pedal (12), a spring (13), an upper step (22), while the pneumatic motor (A) and the lifting-lowering mechanism (B) are interconnected by means of a flexible cable (23) and a hose (25).
