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.

1. A quick safety connection for selectively connecting pipes and fluid communication, the safety connection comprising a male connector and a female element, said male connector being of a size to be selectively received within a central bore of said female element, a sleeve slidably disposed about said female element so as to be axially movable relative thereto between a first position wherein said male connector is fully connected to said female element to an intermediate discharge position as said sleeve is moved toward said female element wherein said male connector is partially spaced from but connected to said female element, means for limiting movement of said sleeve at said intermediate discharge position, said means for limiting including an annular space defined between a portion of said female element and said sleeve, a stop disposed within said annular space and being engageable by tab means carried by said sleeve when said sleeve is moved in a direction toward said female element, at least one fluid path in said female element to permit fluid entry into said annular space when said sleeve is moved from said first position to said intermediate discharge position wherein fluid is permitted to be discharged from between said male connector and said female element to a surrounding atmosphere and such that a fluid pressure is created within said annular space to provide a force to urge said stop against said tab means of said sleeve to thereby oppose movement of said sleeve toward said male connector to thereby retain said sleeve in said intermediate position and prevent the release of said male connector from said female element until pressure between said male connector and said female element is reduced to a safe level to permit said male connector to be fully disconnected from said female element by subsequent movement of said sleeve toward said male connector, locking means movably disposed between said male connector and said female element for retaining said male connector in said first position, and retention means for releaseably retaining said male connector to said female element when said sleeve is moved to said intermediate discharge position.
