Claims (1)

[Claims for Utility Model Registration] (1) A passageway having a longitudinal axis and an open end;
a tubular recess configured within the passageway adjacent the open end and defined axially by axially spaced radially inner and outer shoulders; a female component; a male component having an elongated cylindrical tip received axially within an open end of a passageway of the female component; an inner ring received within the recess; and an outer ring;
a plurality of axially extending spacer fingers maintaining an axial spacing between said inner ring and said outer ring and extending uniformly between said rings; a radially contractible spring steel sheet retainer comprising a plurality of elongated elastic fingers having radially deflectable free ends extending longitudinally in the facing direction and located radially inwardly; The retainer has a normal diameter that is greater than the diameter of the recess such that when radially contracted, the retainer has the inner ring adjacent the inner shoulder and the outer ring received within the recess adjacent to the outer shoulder and resiliently maintained within the recess, the free ends of the resilient fingers extending radially obliquely toward the passageway axis; engaging the free ends of the resilient fingers to prevent the cylindrical tip from exiting the passageway when the cylindrical tip of the mold part is inserted a predetermined axial distance into the passageway; an annular shoulder formed on the cylindrical tip of the male part; a sealing device disposed between the cylindrical tip and the passageway; and an elastic finger provided on the male part. a resilient finger release device received within the open end of the female component for selectively engaging the free ends of the fingers; a latching position that allows engagement with a shoulder and a latching position that engages and frees said elastic fingers to allow said cylindrical tip to be removed from the open end of said passageway; A releasable push-on coupling characterized in that it is axially movable between alignment and engagement with the annular shoulder and a release position in which the end is moved radially outwardly. (2) In the coupling device according to claim 1, the elastic finger release device has an inner end that is received within the open end of the female part, and a connector that connects the finger to the annular shoulder. a releasable push-on coupling comprising an annular sleeve having an externally accessible outer end when engaged with the male and female parts to interconnect said female and male parts. (3) Utility model registration In the connector according to claim 2, the male part is formed with a cylindrical surface coaxial with the tip of the male part, and the sleeve slides on the cylindrical surface. A releasable push-type coupling characterized in that: (4) In the coupling device according to claim 3 of the utility model registration claim, the coupling device is formed on the circumference of the cylindrical surface of the male part and extends axially from the annular shoulder portion and extends radially outward. A releasable push-fit coupling comprising an elongated annular boss, said boss limiting axial movement of said sleeve on said cylindrical surface away from said annular shoulder. (5) In the coupling device according to claim 4 of the utility model registration claim, the sleeve is made of an elastic material;
A slit is formed in the sleeve in the axial direction to temporarily bend the sleeve to increase the inner diameter of the sleeve so that the sleeve can be inserted from above the boss and fitted onto the cylindrical surface. A releasable push-type coupling characterized by: (6) A releasable push-in connector according to claim 3, wherein the sleeve is made of a synthetic resin material. (7) A releasable push-in connector according to claim 3, wherein the sleeve has a generally uniform thickness over its entire length.
