FIELD: machine building.
SUBSTANCE: invention relates fluid coupling comprising: socket (14) and plug (12) and is intended for connection of two fluid hoses, wherein plug (12) has neck (18), which is adapted to be inserted into the socket (14), said neck comprising annular groove (62) for engaging locking element (66) in the socket. Locking element (66) comprises a push-button (68), adapted to be actuated in a radial manner from an exterior of the socket (14), two flexible fork arms (70) protruding from the push-button, and being adapted to engage into hub (72) of socket (14), diagonal ramp surfaces (90) on two opposing inner faces being defined on the flexible fork arms, and being adapted to engage around the neck (18) in an area of annular groove (62) on portion of its perimeter. Annular groove (62) is delimited by two opposing and diverging diagonal surfaces (64).
EFFECT: invention simplifies the process of connecting and disconnecting the two liquid hoses.
