<p>A safety mechanism, in particular for movement devices used on boats, such as motor-driven hinges for sliding doors of hulls, adapted for allowing the quick and safe release of a main movement pin (10) of the hinge, in the event of danger and/or damage, comprising a knurled knob (11), associated to the movement pin (10), the rotation of which allows raising the main body of the pin (10) which, in this way, comes out of the hub (5) and detaches the contact portion from the pinion (34) of the gearmotor (35), the latter in turn connected to the electrical motor (36) for moving the pin (10).
