The invention relates to a pull-out guide for pulling out an extractable furniture part (5) from a furniture carcass (4), the pull-out guide comprising a first rail (1) and a second rail (2), wherein the pulling of the first rail (1) out of the second rail (2) is limited by a stop element (13) of the first tail (1) striking a pull-out stop (12) of the second rail (2). A securing part (14) is mounted on the second rail (2) so as to be rotatable about an axis of rotation (15), which securing part can be rotated, counter to the force of a spring element (16), from a blocked position, in which lifting of the front end of the first rail (1) is blocked, in a rotational opening direction into a release position, in which the front end of the first rail (1) can be lifted and the stop element (13) of the first rail (1) can be moved over the pull-out stop (12) of the second rail (2). A holding device is provided which, in a holding state, holds the securing part (14), totaled into the release position, in the release position.
