Valve including a closing device and sealed connectors

A valve for controlling the flow of a fluid, comprising:

• (A) a valve body having a fluid channel and an inner cavity formed therein, said inner cavity having a geometrical axis which is substantially normal to the longitudinal axis of said fluid channel, said valve body further having an opening formed therein which lies in a plane which is substantially normal to said geometrical axis;
• (B) a closing device having a movable closing member and a support which receives said closing member and which delimits a channel which is aligned with said fluid channel, said closing device being received in said inner cavity upon insertion of said closing device through said opening;
• and
• (C) a connector device for connecting said support to said valve body, said connector device being sealed from the ambient environment and from said fluid, said connector device including
• a fixed element comprising at least one rest formed in said valve body and being open to said inner cavity, and
• a movable element including a locking piece which is mounted in said support and which is radially movable within said support with respect to said geometrical axis, and
• an actuating member which is movable with respect to said valve body and which moves said movable element radially with respect to said geometrical axis from a first, locking position remote from said geometrical axis in which said locking piece is at least partially positioned in said rest to lock said closing device within said valve body, to a second position which is closer to said geometrical axis than said first position and in which said locking piece is located in the support to enable insertion and removal of said closing device into and out of said inner cavity.
