An anti-play nut which comprises two tapped parts (1, 2), axially movable in relation to one another and cooperating with the thread of a screw or the like, is characterized in that each of the two tapped parts (1, 2) has a bearing surface (5, 6), whereby the two bearing surfaces are convergent in relation to each other, at least one being slanted at an angle other than 90 DEG in relation to the common axis of the screw and the nut; a wedge (7) having lateral faces (8, 9) with the same inclination as said bearing surfaces (5, 6) cooperates with the latter; resilient means (10) radially acts on the wedge (7) so that the lateral faces (8, 9) of the latter cooperate with said bearing surfaces (5, 6) in order to axially displace said two tapped parts (1, 2) in relation to one another, and a resilient element (13) connects the two tapped parts (1, 2) for rotationally tight-coupling them and for axially biasing them against the elastic effect of wedge (7).
