A quick-disconnect device for coupling segments of a diver's umbilical ho includes separable rectangular bodies carrying complementary hose couplings spaced therealong. The bodies, which have nested rim and reduced portions, are biased toward separation by a rectangular, flat-type spring and releasable retained against separation by a retractable retaining pin extending diagonally therethrough and normally locked against retraction by partial rotation.

1. A diver's life support umbilical quick-disconnect device for coupling and uncoupling a plurality of first hoses and a like plurality of second hoses, said device comprising: a first generally rectangular body; a plurality of first hose coupling elements extending through said first body and disposed in spaced, side-by-side parallel relation along the long axis of said first body with their corresponding coupling element engaging ends located on one side of said first body; means defining a rim around the peripheral portion of said one side of said first body; a second generally rectangular body having a main portion and a reduced portion defining therebetween a peripheral shoulder extending about said second body, said reduced portion being received in said rim; a plurality of second hose coupling elements extending through said second body and disposed in spaced, side-by-side parallel relation along the long axis of said second body with their corresponding coupling element engaging ends engaged with the coupling element engaging ends of said first hose coupling elements; a plurality of sealing means, each operative to provide a seal between corresponding ones of said first and second coupling elements; spring means, disposed between and compressed by said shoulder and said rim for urging said bodies away from one another; and retainer means, cooperating with said first and second bodies for holding said bodies together against the urging of said spring means, said retainer means being actuable to release said bodies for movement away from one another under the influence of said spring means so as to disengage said coupling elements. 2. A device as defined in claim 1, and wherein: said spring means comprises a generally rectangular spring member formed from flat stock and having a central opening receiving said reduced portion of said second body. 3. A device as defined in claim 2, and wherein: said rim and said reduced portion have diagonal openings that are aligned transversely of said device; said retainer means comprises a retaining pin extending through said aligned diagonal openings; said retaining pin being retractable by force along the axis of said pin member so as to release said bodies for separation by said spring member. 4. A device as defined in claim 3, and wherein: said first hose coupling elements comprise at least three elements having unequal spacing along said long axis of said first body; and said second hose coupling elements comprise at least three elements having corresponding unequal spacing along the long axis of said second body; and said retaining pin passes diagonally between at least two of said coupling elements. 5. A device as defined in claim 4, and wherein: said means defining said rim comprises first and second ears projecting from opposite sides of said rim at diagonal locations with said diagonal openings of said rim extending therethrough; said retaining pin is characterized by a groove having an axially extending portion and a circumferentially extending portion; and means associated with at least one of said ears and cooperating with said groove for alternatively locking said pin member against axial movement when said pin is in a first rotative position, and allowing said axial movement when the pin is in a second rotative position. 6. A device as defined in claim 5, and wherein: said retaining pin is characterized by a plurality of axial and circumferential grooves; and said means for alternately locking against and allowing axial movement of said pin comprises first and second groove engaging elements associated with said first and second ears, respectively, and projecting into said diagonal openings therein for cooperation with said grooves of said pin. 7. A device as defined in claim 6, and wherein: at least one of said groove engaging elements is operative to limit retraction of said retaining pin completely from said rim. 8. A device as defined in claim 7, and wherein: said retaining pin is characterized by a round-shaped handle for facilitating said rotation and retraction thereof.
