Abstract:
A locking device comprising:a support plate;an annulus in contact with the support plate;a cam housed to rotate in the annulus about a central axis and designed to be mounted to rotate with an outlet member, the cam and the annulus defining at least one running path of varying section;a control member mounted to rotate relative to the support plate about the central axis;locking means mounted to move in the running path, said locking means being normally in a locked state in which they co-operate with the annulus and the cam to prevent any relative rotary movement of said cam relative to the support plate in the absence of the control member being actuated, said control member being adapted to act on the locking means by placing them in an unlocking state in which they allow the cam to rotate relative to the support plate; anda closure ring partially defining a housing which encloses the cam and the locking means, said closure ring being fixed to the support plate,wherein the closure ring is in the form of a simple plate which covers axially at least the annulus on its side remote from the support plate and which extends axially towards said support plate via tabs holding the annulus captive, said tabs being secured to the support plate, and the annulus resting directly against said support plate.
