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 co
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 ).

1. A connecting member ( 4 , 4 ′) connectable to a first conduit ( 2 ) for conducting a pressurized operating fluid, and fittable releasably to an endpiece ( 5 ) of a second conduit ( 3 ) for conducting said operating fluid, so as to define a fast-fit safety coupling ( 1 ); said connecting member ( 4 , 4 ′) having a longitudinal axis (A) and comprising:a substantially tubular main member ( 10 ) connectable to said first conduit ( 2 );a slide valve member ( 11 ) fitted inside said main member ( 10 ) so as to slide axially between a first work position wherein said valve member ( 11 ) separates said first conduit ( 2 ) in fluidtight manner from the outside, and a second work position permitting fluid flow between said first and said second conduit ( 2 , 3 );first retaining means ( 18 ) for releasably connecting said endpiece ( 5 ) to said valve member ( 11 );second retaining means ( 17 ) for releasably connecting said valve member ( 11 ), in said second work position and connected to said endpiece ( 5 ), to said main member ( 10 ); andcontrol means ( 70 , 70 ′, 71 , 71 ′, 72 , 54 ) for disconnecting said connecting member ( 4 , 4 ′) and said endpiece ( 5 ) by successively releasing said second retaining means ( 17 )—thus moving said valve member ( 11 ) into said first work position and permitting outflow of the operating fluid between said main member ( 10 ) and the endpiece ( 5 )—and said first retaining means ( 18 ); said control means ( 70 , 70 ′, 71 , 71 ′, 72 , 54 ) comprising a first actuating member ( 70 , 70 ′) fitted in angularly fixed manner to said valve member ( 11 ) and movable axially with respect to the valve member ( 11 ) in opposition to elastic return means ( 66 ) to release said first retaining means ( 18 );characterized in that said control means ( 70 , 70 ′, 71 , 71 ′, 72 , 54 ) comprise a second actuating member ( 71 , 71 ′), which is axially fixed and rotatable with respect to said valve member ( 11 ) at least in said first work position of the valve member ( 11 ); and cam transmission means ( 72 ) interposed between said first and said second actuating member ( 70 , 70 ′, 71 , 71 ′) and for converting rotation of said second actuating member ( 71 , 71 ′) into axial displacement of said first actuating member ( 70 , 70 ′) in opposition to said elastic means ( 66 ). 2. A connecting member as claimed in claim 1, characterized in that said valve member ( 11 ) has an inner cavity ( 27 ) engaged, in use, by said endpiece ( 5 ); and in that said first retaining means ( 18 ) comprise a number of engaging members ( 60 ), which are mounted to slide inside respective seats ( 61 ) formed in a lateral wall ( 26 ) of said valve member ( 11 ) defining said cavity ( 27 ), are pushed by said elastic means ( 66 ) into a coupling position engaging an annular groove ( 7 ) on said endpiece ( 5 ), and are moved into a release position releasing said groove ( 7 ) on said endpiece ( 5 ) by the thrust generated by said first actuating member ( 70 , 70 ′ ) moving axially in opposition to said elastic means ( 66 ). 3. A connecting member as claimed in claim 2, characterized in that said engaging members ( 60 ) are located between said elastic means ( 66 ) and said first actuating member ( 70 , 70 ′). 4. A connecting member as claimed in claim 3, characterized in that said engaging members comprise two transverse bars ( 60 ) extending parallel to each other on diametrically opposite sides of said longitudinal axis (A). 5. A connecting member as claimed in claim 1, characterized by comprising disabling means ( 76 , 79 , 104 , 105 ) for preventing rotation of said second actuating member ( 71 , 71 ′) and which are selectively deactivated in said first work position of said valve member ( 11 ). 6. A connecting member as claimed in claim 5, characterized in that said disabling means comprise spline d coupling means ( 79 , 76 ) between said second actuating member ( 71 ) and said main member ( 10 ), and which are deactivated by movement of said valve member ( 11 ) into said first work position. 7. A connecting member as claimed in claim 1, characterized in that said cam transmission means ( 72 ) comprise a first and a second surface ( 80 , 81 ) mating with each other and formed on said first and said second member ( 70 , 70 ′, 71 , 71 ′) respectively. 8. A connecting member as claimed in claim 7, characterized in that said first surface ( 80 ) comprises a number of troughs ( 82 ), and said second surface ( 81 ) comprises a number of crests ( 84 ) corresponding in shape to that of said troughs ( 82 ). 9. A connecting member as claimed in claim 8, characterized in that said troughs ( 82 ) and said crests ( 84 ) have respect V-shaped profiles. 10. A connecting member as claimed in claim 8 or 9, characterized in that said first and said second surface ( 80 , 81 ) comprise a number of flat portions ( 83 , 85 ) alternating with relative said troughs ( 82 ) and relative said crests ( 84 ) respectively.
