The invention relates to a device (1) for delivering two predetermined doses of a product (3), comprising: —a container (2) for containing said product, said container having a distal end (2d) through which the product is delivered under the distal pressure of a piston, —a pusher (7) movable with respect to said container for causing said piston (4) to move in the distal direction from an initial position, in which none of said product has been expelled to a first position, in which a first dose of said product has been expelled, and to a second position, in which a second dose of said product has been expelled, —a holder body (15) receiving said container and said pusher (7), —biasing means (22) for urging said pusher (7) in the distal direction, from the initial to the first position, and to the second position, —first and second retaining means (9, 11, 19) for maintaining said pusher (7) in said initial position, and in said first position, —first and second actuation means (18) to deactivate said first and second retaining means (9, 11, 19), characterized in that said first and/or second actuation means (18) are at least rotationally displaceable, said rotation causing at least part of the deactivation of said first and/or second retaining means (9, 11, 19).
