The present invention relates to a female coupling and the respective female-male connector, the female coupling being adapted to be connected to and disconnected from a corresponding male coupling by means of pushing and pulling actions, respectively, said female coupling and male couplings comprising a female valve assembly and a male valve assembly respectively, each of said female and male valve assemblies being adapted to be alternatively translated forwards and backwards between a first closing position and a second opening position, wherein the flow of a fluid is possible between the female coupling and male coupling with said female and male valve assemblies in the respective opening positions, wherein said female coupling comprises mechanical locking means adapted to prevent the accidental switching of said female valve assembly from its said second opening position to its first closing position even in case of fluid flow from the male connector to the female connector.

Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.

A circuit breaker for a facility for handling pressurized fluid includes a male element and a female element. The male element includes a male body defining a first inner pipe, having a member for closing off the front end of the first pipe from at least one first radial passage of a movable valve, and a locking notch arranged on the male body. The female element includes a female body defining a second inner pipe and provided with at least one radial passage, a movable valve and several locking members movable between a first radial position, for the axial locking of the male and female bodies in the coupled configuration, and a second radial position, where the locking members free the passage of the male body in the female body. In the coupled configuration, the radial passages are in communication, while sealing gaskets cooperate radially with male and female bodies.

A coupling member inhibits accidental pivoting of a lever for operating a movable member such as a chuck member or a valve. The coupling member has a chuck member mounted displaceably relative to a female coupling body between a temporarily connecting position (first position) and a connecting position (second position). The chuck member is operated by a lever that is pivotable relative to the female coupling body. When the lever is pivoted from a first pivoting position to a second pivoting position, the chuck member is displaced from the temporarily connecting position to the connecting position to connect an associated male coupling member. When the lever is in the second pivoting position, a lock member of the lever engages a lever holding member to inhibit the lever from pivoting toward the first pivoting position.
