Fluidic connection device for a fluid circuit of a motor vehicle

A fluidic connection device for a fluid circuit, comprising:

• a female fluidic connector comprising a housing configured to receive a male fluidic connector by translation along an axis (A);
• a U-shaped lock carried by the female connector and comprising a pair of elastically deformable legs, the pair of elastically deformable legs being arranged substantially in a first plane, perpendicular to the axis (A) and on either side of the axis (A) and being configured to cooperate by elastic snap-fitting with the male connector to ensure retention of the male connector in the female connector along the axis (A);
• and
• a locking indicator carried by the female connector and configured to be moved in translation in a direction, perpendicular to the axis (A), between a first position for releasing the U-shaped lock and a second position for locking the U-shaped lock,
• wherein the locking indicator comprises a first pair of legs and a second pair of legs, the first pair of legs being separated from the second pair of legs, and the first pair of legs having an elastic deformation capacity by displacement from one another, which is different from an elastic deformation capacity of the second pair of legs,
• wherein the first pair of legs are configured to cooperate by elastic deformation with the male connector, from a first substantially free position without constraint, wherein the first pair of legs cooperate with the female connector to forbid a translation of the locking indicator in said direction, up to a constrained position, wherein the locking indicator is configured to be moved in translation in said direction,
• wherein the second pair of legs are configured to cooperate by abutting with the U-shaped lock to limit their displacement, when the locking indicator is in the second position,
• and wherein the locking indicator comprises a third pair of legs which are separated from the first pair of legs and the second pair of legs, and which have an elastic deformation capacity by displacing one from the other, the elastic deformation capacity of the third pair of legs being different from the elastic deformation capacity of at least one of the first pair of legs or the second pair of legs, the third pair of legs being configured to cooperate by elastic snap-fitting with the female connector to retain the locking indicator opposite the female connector in translation in said direction.
