The device comprises a gear shift lever which is supported on a stationary support casing and includes a rod having an upper straight section, an upper sleeve fixed to the upper straight section of the rod, and a lower sleeve mounted on the upper straight section of the rod so that it can slide between a lower end-travel position and an upper end-travel position. The lower sleeve is provided with a male stop element arranged to releasably engage a female stop element provided on the stationary support casing, in such a manner as to lock the gear shift lever in a predetermined reference position. According to the invention, the lower sleeve is arranged to rotate between a first angular position, in which the male stop element is aligned with the female stop element in the vertical direction of sliding of the lower sleeve, and a second angular position, in which the male stop element is rotated 90 degrees relative to the female stop element. The movement of the lower sleeve from the reference position to the normal operating position of the gear shift lever thus consists of both a translation and of a rotation.
