Quick connector coupling

The quick connector coupling comprising:

• a connector body defining a through bore extending axially rearward from an entrance;
• a tube received within said bore with a radially enlarged upset;
• a primary retainer disposed in said bore having a primary retainer ring and two primary retainer arms located axially forward of said primary retainer ring, each of said primary retainer arms in abutting relationship with said upset;
• and
• a secondary retainer disposed in said bore having a secondary retainer ring and two secondary retainer arms located axially rearward of said secondary retainer ring, each of said secondary retainer arms located circumferentially in between two primary retainer arms and in abutting relationship with said upset
• wherein said connector body defines an alignment slot and said secondary retainer includes an alignment tab extending radially outward from said secondary retainer ring, said alignment tab is positioned in said alignment slot.

The quick connector coupling

• comprising:
• a connector body defining a through bore extending axially rearward from an entrance;
• a tube received within said bore with a radially enlarged upset;
• a primary retainer disposed in said bore having a primary retainer ring and two primary retainer arms located axially forward of said primary retainer ring, each of said primary retainer arms in abutting relationship with said upset;
• and
• a secondary retainer disposed in said bore having a secondary retainer ring and two secondary retainer arms located axially rearward of said secondary retainer ring, each of said secondary retainer arms located circumferentially in between two primary retainer arms and in abutting relationship with said upset
• wherein each of said primary retainer arms includes a radially inner section, a radially outer section and a rear bend connecting said radially inner section with said radially outer section, and wherein said radially inner section is in abutting relationship with said upset
• wherein each of said radially inner sections includes braces extending circumferentially from each circumferential side of the radially inner section.

A quick connector coupling for forming a severable connection in a fluid line including a tube, said coupling comprising a connector body, comprising:

• a stem defining an axially extending through bore;
• and
• a separate cap permanently secured to said stem, said cap defining an axially extending through bore;
• wherein one of said stem and said cap includes an axially extending annular rib located radially outward of said bore of one of said stem and said cap, other of said stem and said cap includes an annular groove located radially outward of said bore of other of said stem and said cap, said annular rib is positioned in said annular groove;
• said connector body defining a though bore extending axially rearward from an entrance;
• said body having a lip defining a rearward facing annular abutment surface;
• a primary retainer disposed in said bore having a primary retainer ring and two primary retainer arms located axially forward of said primary retainer ring, each of said primary retainer arms adapted for an abutting relationship with an upset on the tube;
• and
• a secondary retainer disposed in said bore having a secondary retainer ring and two secondary retainer arms located axially rearward of said secondary retainer ring, in abutting relation to said rearward facing annular abutment surface of said lip of said connector body with each of said secondary retainer arms located circumferentially in between two primary retainer arms and adapted for abutting relationship with the upset on the tube.

A quick connector coupling for forming a severable connection in a fluid line comprising:

• a connector body including a stem and a separate cap permanently secured to said stem, said connector body defines two annular surfaces and an entrance to a through bore extending axially through said connector body;
• and
• a primary retainer disposed in said bore between said annular surfaces having a primary retainer ring and two primary retainer arms located axially forward of said primary retainer ring,
• a secondary retainer disposed in said bore between said annular surfaces having a secondary retainer ring and two secondary retainer arms located axially rearward of said secondary retainer ring, each of said secondary retainer arms located circumferentially in between two primary retainer arms.
