Abstract: The invention relates to a device for the actuation of the valve of a flush tank: a movable vertical tube (8) carries a valve (7). A linking rod (9) controls the movement of the tube, a lever (12) operates the linking rod, a member (16) operates a rod (15), which in turn controls the lever (12). The rod (15) is connected to the lever (12) and to the operating member (16), the operating member having two positions, one being the opening position (26), and the other one being the closing position (27), and the passage of the member from one to the other one of these positions, controlled by the user, bring about the correlative passage of the valve (7) from one (26") to the other one (27") of the positions and inversely.

Abstract: An element adapted to engage a rod is composed of a tough synthetic-resin material and is tubular so as to receive the rod. Relatively long slots opening at one end of the element are aligned with relatively short slots opening at the opposite end of the element so that the opposite end of the element is formed with jaws which can be spread apart when members defined between the long slots are pressed together in a pincer movement. The inner surfaces of the jaws are provided with formations engageable with complementary formations on the rod.
