A device for towing very long tubular objects comprising: - pulling means (12, 13, 14) capable of driving, by friction, the object in a towing direction, - gripping means (110, 112, 113) capable of exerting a load on the pulling means to keep the pulling means and the towed object in continuous contact; the gripping means being driven by a relative movement relative to the towed object in a direction opposite to the towing direction, - driving means (115, 116) capable of driving the pulling means (12, 13, 14) and the gripping means (110, 112, 113) in a coordinated manner to ensure a continuous and uniform pulling of the object, the pulling means (12, 13, 14) comprise a tread coming into contact with the object to be towed, produced in a material with strong adhesive power, the gripping means (110, 112, 113) comprise two main pulleys (112, 113) and a belt taut between the two main pulleys (112, 113) and helically wound around the object to be towed and the tread, so as to exert a load on the tread to keep the tread in continuous contact on the object to be towed, characterized in that it further comprises setting means (30, 31), capable of adjusting the load exerted by the gripping means (110, 112, 113) on the pulling means, the setting means (30, 31) comprise a return pulley guiding the belt and being able to be displaced relative to the two main pulleys (112, 113), so as to adjust the tension of the belt, making it possible to adjust the load exerted by the tread on the object to be towed, the return pulley being able to be displaced between a first and a second determined position so as to make it possible to exert on the object to be towed a load lying between a minimum value close to zero and a predetermined maximum value. - pulling means (12, 13, 14) capable of driving, by friction, the object in a towing direction, - gripping means (110, 112, 113) capable of exerting a load on the pulling means to keep the pulling means and the towed object in continuous contact; the gripping means being driven by a relative movement relative to the towed object in a direction opposite to the towing direction, - driving means (115, 116) capable of driving the pulling means (12, 13, 14) and the gripping means (110, 112, 113) in a coordinated manner to ensure a continuous and uniform pulling of the object, the pulling means (12, 13, 14) comprise a tread coming into contact with the object to be towed, produced in a material with strong adhesive power, the gripping means (110, 112, 113) comprise two main pulleys (112, 113) and a belt taut between the two main pulleys (112, 113) and helically wound around the object to be towed and the tread, so as to exert a load on the tread to keep the tread in continuous contact on the object to be towed, characterized in that it further comprises setting means (30, 31), capable of adjusting the load exerted by the gripping means (110, 112, 113) on the pulling means, the setting means (30, 31) comprise a return pulley guiding the belt and being able to be displaced relative to the two main pulleys (112, 113), so as to adjust the tension of the belt, making it possible to adjust the load exerted by the tread on the object to be towed, the return pulley being able to be displaced between a first and a second determined position so as to make it possible to exert on the object to be towed a load lying between a minimum value close to zero and a predetermined maximum value.
