Abstract: A connecting member (4) for a fast-fit safety coupling (1), having a tubular main member (10) connectable to a first conduit (2) for conducting pressurized fluid; a valve member (11) fitted inside the main member (10) to slide axially between a first work position separating the first conduit (2) in fluidtight manner from the outside, and an open second work position; first retaining means (18) for releasably connecting an endpiece (5) of a second conduit (3) to the valve member (11); second retaining means (17) for releasably connecting the valve member (11), in the second work position and connected to the endpiece (5), to the main member (10); and control means (70, 71, 72, 54) for disconnecting the connecting member (4) and the endpiece (5).
