1. A connecting device of a tube end section, comprising:
a tubular body defining a channel provided with retaining means, including a hooking element for engaging an outer surface of the tube end section, and an annular seal for gripping the outer surface of the tube end section, characterized in that the device comprises at least a first arm having an end arranged in the channel to be actuated by the tube end section downstream of the retaining means so as to make a portion of the arm a connection indicator which is detectable from outside the body and a free end which is movable in a substantially axial direction between a visible position in which the free end can be seen from the outside of the body and a retracted position in which the free end is concealed from the outside of the body;
wherein the substantially axial direction corresponds to a direction of insertion of the tube end section in the body.
