Abstract

Gun for connecting one pipe to another with a larger diameter, which is specially designed to carry out the locking of the radial connection device object of the utility model 274.946 to the hole previously made in the pipe with the largest diameter, essentially characterized in that in the same a main body or support tube is defined, assisted by the corresponding handles and trigger lever, in whose support tube are coaxially mounted two axes, one internal and fixed and one enveloping and mobile, the first of them being provided close to its free end of a tapered narrowing, in correspondence with which the movable shaft has two radially projecting cams when said movable shaft is retracted by the actuation of the lever of the gun, all in such a way that both axes assume in rest condition a generally cylindrical configuration and are able to receive coaxially to the di radial connection device and to access with it to the inside of the pipe of greater diameter, through the hole made to the affection in the same, until a limit situation in which the mole of the insert of the device impinges on the embouchure of the orifice, while, from such a situation and acting on the actuating lever, the mobile axis is retracted, the cams project radially and drag the bushing of the connection device into the insertion sector of the latter, causing its radial deformation and its perfect and hermetic adjustment with respect to the hole of the largest diameter pipe.
