Abstract: A female snap-on connector (1) intended to cooperate with a male attachment end fitting (20) of the type with a central bush (26) and a flange (25) includes a body (2) forming a cylindrical cavity and to which is fixed a cap (10) forming a housing for two symmetrical latch parts (50) disposed head-to-spigot, mounted to slide in the same transverse direction, each latch part (50) including a manoeuvring part (51), a rigid connecting rod (53) and a jaw (52) as well as spring means (55) for continuously urging each latch part (50) elastically into its rest position in which the jaw (52) is moved toward the axis and the manoeuvring part (51) is in its radially outermost position.

Abstract: The invention provides a coupling endpiece engageable by force in a corrugated end of a corrugated tube having corrugations following one another at a predetermined pitch and possessing a minimum inside diameter and a maximum inside diameter. The endpiece is constituted by a tubular body possessing a first zone provided on the outside with at least two annular barbs of the Christmas-tree type that are spaced apart by a distance corresponding to the pitch of the corrugations of the tube and having a maximum diameter greater than the maximum inside diameter of the tube, the first zone presenting between the barbs a minimum diameter greater than the minimum inside diameter of the tube, and the body has a second zone extending immediately behind the barbs to receive at least one end corrugation of the tube and having an outside diameter less than a diameter of a junction zone between two annular barbs. The invention also provides a corrugated tube fitted with such an endpiece.

Abstract: A heat exchanger comprising a fluid transport tube shaped to form a coil, the tube being made of a thermoplastic material and comprising at least one corrugated segment. Cooling circuit, fuel circuit and vehicle comprising such a heat exchanger.
