Abstract: A safety device for a mechanical gearbox, comprising a gear lever-operated internal control shaft (2) translatable to select a gear change line, and rotatable to engage a gear on the selected line, a gear change pin (3) secured to the internal control shaft (2), a set of dogs (6a, 6b, 6c, 6d) including at least one special forward gear dog (6c) and a reverse gear dog (6d), said dogs being adjacent and moved on either side of their neutral line and in opposite directions to engage the highest forward gear and the reverse gear, respectively. Said device includes means for guiding the gear change pin (3) in such a way as to prevent insertion thereof into the reverse gear dog (6d) when the special forward gear dog (6c) is realigned with the other forward gear dogs (6a, 6b).
