<p>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). The control means have a first actuating member (70) fitted in angularly fixed manner to the valve member (11) and movable axially, with respect to the valve member and upon deactivation of the second retaining means, to release the first retaining means (18); a second actuating member (71) connected in axially fixed, rotary manner to the valve member (11); and cam transmission means (72) for converting rotation of the second actuating member (71) into axial displacement of the first actuating member (70) to release the endpiece (5).</p> |
