Abstract
A quick safety connection for the removable joining of pipes, comprising a male connector and a female element adapted to fit and to be locked inside one another. A controlled locking mechanism is adapted to immobilized the male connector axially in a position of connection, while at least one retention member is provided to immobilize the male connector, after release of the connector by said locking mechanism, in an intermediate position of discharge of the pipe connection. The locking mechanism and retention member are controlled by a sleeve sliding around the female element. Vents and safety stops are provided to limit the movement of the sleeve under the effect of the pressure prevailing due to the discharge of the connection in the intermediate position between the female element and the sleeve.
