Abstract

A quick connector has a pair of waist segments, a shoulder segment, a body segment with an aperture therein, and a leg segment. The leg segment is defined by a pair of projecting elements which are at least partially compressible toward one another thereby causing the pair of waist segments to move toward one another. Thus, a swivelable connection is made which has the equivalent length and diameter of a convention nonswivelable threaded coupling. The quick connector may be released by hand or a snap ring tool inserted into holes.

Claims

1. A quick connector used to couple a male conduit to a female receptacle, said female receptacle having a bore centrally extending therethrough defined by an inside surface therein, said quick connector comprising:

a body segment having an aperture therethrough defined by an inner edge therearound, said inner edge of said body segment surrounding a predetermined portion of said male conduit therewithin;

a pair of waist segments each having an interior edge thereabout, said body segment coupled to said pair of waist segments;

interface portions mounted on said pair of waist segments which attachably engage said female receptacle thereagainst;

a leg segment attached to said pair of waist segments clear of said aperture within said body segment thereof, said leg segment defined by a pair of projecting elements each extending substantially perpendicular to said pair of waist segments such that said leg segment is orientated substantially parallel with a longitudinal axis of said male conduit adjacent thereto; and

said leg segment protruding through said bore of said female receptacle so as to be accessible from thereout, said interface portions insertable into said bore of said female receptacle by allowing said pair of projecting members of said leg segment to at least partially compress toward one another, said leg segment further urging said interface portions radially outward so as to be engagably coupled within said female receptacle, said interface portions being disengagable from said female receptacle by at least partially compressing said projecting members of said leg segment toward one another whereby said quick connector can be longitudinally removed from said female receptacle.

2. The quick connector of claim 1 further comprising:

a locking member having a finger extending therefrom insertable and removable between said pair of projecting elements of said leg segment, when inserted said locking member preventing said pair of projecting elements of said leg segment from being compressible toward one another and also preventing said pair of shoulder segments from compressing toward one another thereby preventing inadvertent disengagement of said quick connector from said female receptacle.

3. The quick connector of claim 2 wherein said locking member provides a visual indication that assembly of the connector is complete.

4. The quick connector of claim 2 wherein said locking member, when disposed in said position preventing said pair of projecting elements of said leg segments from being compressible, provides a visual indication that the connector is assembled.
