A positioning device for a remote control of a heavy duty vehicle or agricultural vehicle includes an elastic element. The elastic element has a fastening portion, configured to be secured to a body of the remote control, and a retaining portion, arranged to cooperate with an actuator of the remote control at a threshold position delimiting a first portion of a displacement trajectory of the actuator, and a second portion of the displacement trajectory, so as to oppose movement of the actuator according to its displacement trajectory along at least one displacement direction upon switching of said threshold position and allow switching at the threshold position in said displacement direction as a result of application of a threshold switching force exerted on the actuator. The threshold switching force is higher than a displacement force necessary for movement of the actuator on the first or second portion of the displacement trajectory.
