A quick connector coupling (10) comprising a connector body (12), a primary retainer (26), a secondary retainer (28) and a male member (30) having a radially enlarged upset (38). The connector body includes a stem (14) and a separate cap (16) permanently secured to the stem (14). The stem (14) defines an axially extending through bore and includes an annular rib (78) located radially outward of the bore. The cap defines an annular groove (110) located radially outward of the bore. The annular rib (78) of the stem (14) is positioned in the annular groove (110) of the cap (16). The cap (16) is spin welded to the stem (14) to permanently secure the cap (16) to the stem (14). The connector body (12) further defines two annular abutment surfaces (57,103). The primary retainer (26) and the secondary retainer (28) are located axially in between the two annular abutment surfaces (57,103) of the connector body (12) . The primary retainer (26) has a ring (122) and two primary retainer arms (124) located axially forward of the ring (122). Each primary retainer arm (124) is in abutting relationship with the upset (38). The secondary retainer (28) has a ring (140) and two secondary retainer arms (142) located axially rearward of the ring (140). Each secondary retainer arm (142) is located circumferentially in between the two primary retainer arms (124) and in abutting relationship with the upset (38).
