A quick-coupling device (1) for circuits for circulation of fluids under pressure comprising a socket (2) and a fitting element (3) that can be housed in the socket, the socket (2) including an outer body (5) defining at least part of a first channel (2d) and comprising an annular cavity (5a) opening on the first channel (2d), a substantially annular constraint element (4) at least partly housed in the annular cavity (5a) and movable therein, and including a plurality of constraint sectors (7) made up of circular sectors of the constraint element (4), adapted to be mutually moved in a radial direction and defining a release position at which the constraint element (4) is retracted into the annular cavity (5a) so as to enable movement of the fitting element (3) relative to the socket (2), and a tightening position at which the constraint element (4) secures the fitting element (3) to the socket (2), an extractor (6) partly housed in the outer body (5) and movable along the central axis (2a) relative to the outer body (5) and adapted to move the constraint element (4) from the tightening position to the release position, and comprising teeth (6a) placed between the constraint sectors (7) and suitable to maintain a minimum distance between said constraint sectors (7).
