Device for simplification of renewal of seal of ball joints consists of two identical parts, which are screwed in two opposite sides in the horizontal plane by means of four screws, integral part of the device, to both flanges of the ball joint. Each of the two parts of the device is equipped with two identical L-shaped consoles. On one arm of the console there is a support and a hole, into which one of the four above mentioned screws, equipped with circumferential groove, is inserted. A securing screw interferes with this groove. On the second arm of the console there is a casing into which, near one console, a pressing flange hub is inserted and near the second console a hub of flange of the conical part is inserted. Both hubs are secured against spontaneous slipping from the casings in identical manner by means of retaining rings. The hubs are interconnected by means of clamping bolts. The clamping bolt is close connected with the hub of the pressing flange by means of a pin, which prevents its rotation in the hub. In the hub of the flange of the conical part there is a through cylindrical hole, through which the pin can move freely in axial direction. On the thread of the bolt a stock is screwed, secured against spontaneous release from the bolt by means of appropriate safety lock. The pressing flange is pushed-off by turning the stock anti-clockwise and by the effect of gravity whereas the pressing flange push-in back to original position is performed by turning the stock clockwise.<IMAGE>
