The device for removing a fragment of a nipple from an air line tee in case of a break is made of a single piece of high-strength alloy steel, having a tetrahedral rectangular middle part, in the centre of which there is a through hole; on one side of the middle part there is a tetrahedral truncated pyramid with sharp edges on each face , on the other side of the middle part there is an external groove with an external thread, from the end part of which there is a protruding external groove of a smaller diameter for the impact platform.

EFFECT: creation of a new device, the use of which eliminates the loss of time when eliminating a malfunction that has arisen in the brake or other air line in railway rolling stock along the route, reducing the time for uncoupled repair of a car on general purpose railways and railway stations unsuitable for this purpose, reducing the time of train losses on the Russian Railways network, including the use the device at industrial railway transport enterprises without participation of specially trained workers.
