In an adjustable height towing device, a slide (5) carrying a hook (6) for connecting a trailer is mounted slidably along a pair of guides (7) formed on repetitive uprights of a frame that can be fixed to a tractor. To allow locking of the slide (5) in a plurality of positions along the guides (7), a plurality of engagement seats (9) are provided, arranged on each upright (2) along a longitudinal development direction of the guides (7), and a pair of pins (10) carried by the slide (5) and slidably guided between a locked position in which each is inserted in one of the engagement seats (9), and an unlocking position in which they are unbound from the engagement seats (9). Sensor devices (19) are suitable for detecting the correct insertion of the pins (10) in the respective engagement seats (9) in the locked position.
