A device for a leakproof air-conditioning fluid circuit. A body includes a conduit having a foot at its base, coupled to a communication orifice in the periphery of a tube. A welding is made between an interior part of the base of the foot and a corresponding part of a tube having an orifice. An internal semi-cylindrical a portion of the base of the foot features, around the discharging conduit, a part in the shape of a skirt, formed by two straight or curved segments which together define a semi-cylindrical cradle in the interior wall of the tube. An orifice comprising a whistle-shaped notch in the back of the tube, comprises two complementary segments. |

1. Device intended especially for a leakproof air-conditioning fluid circuit, of the type formed by a body made of injectable material and by a tube, with the said body being crossed axially by a conduit whose head or front end acts as a connecting port, and whose foot into which the conduit discharges is attached by its base, which is largely perpendicular to the axis (XX′) of the conduit, is placed facing a communication orifice that is made in the periphery of the tube made of injected or extruded material through the use of welding or gluing that is performed between, on the one hand, both the interior part of the base of the foot of the device which has a semi-cylindrical curved surface into which the conduit discharges and, on the other hand, a corresponding part of tube located in the area of its orifice, wherein the internal semi-cylindrical part that forms the base of the foot of the device features, in relief, around the discharging conduit, a part in the shape of a skirt that forms a male part that is intended to ensure the rotational and translational positioning of the device, formed by two straight or curved segments that trace an angle at the sharp crest (α) and which are oriented along the longitudinal axis (YY′) of the semi-cylindrical base and which together define, along the transverse axis (ZZ′) of the said base, a semi-cylindrical cradle of radius (r′) that is at most equal to that radius (r) of the internal wall of the tube in the area of its orifice, with this latter being formed by a whistle-shaped notch made in the back of the tube, that forms a female part that comprises, in a manner that is similar to the male part of the device, two complementary segments that trace an angle at the sharp crest (α1) that is identical to the angle at the aforementioned sharp crest (α) and oriented along the longitudinal axis (WW′) of the tube. |
