Abstract

The coupler comprises a male part (10) and a female part (1, 3) having a closure valve (5) at its upstream end, which valve is opened when the female and male parts are coupled together, and is closed during uncoupling thereof. The male part (10) has an outside surface provided with a collar (14). A latch (7) is provided in the female part to move in a radial direction and it includes a bore extending in the axial direction of the female part and through which the male part passes. On the surface of its bore, the latch includes two half-collars (11, 12) at least one of which is formed by two conical surfaces that are essentially sickle-shaped. The surface facing upstream of the half-collar (12) is situated upstream from the collar (14) and is suitable for fitting closely over at least 180° of the collar (14) of the male part when the male part is in a fully coupled position.
