The connector body includes a stem and a separate cap permanently secured to the stem. The stem defines an axially extending through bore and includes an annular rib located radially outward of the bore. The cap defines an annular groove located radially outward of the bore. The annular rib of the stem is positioned in the annular groove of the cap. The cap is spin welded to the stem to permanently secure the cap to the stem. The connector body further defines two annular abutment surfaces. The primary retainer and the secondary retainer are located axially in between the two annular abutment surfaces of the connector body. The primary retainer has a ring and two primary retainer arm located axially forward of the ring. Each primary retainer arm is in abutting relationship with the upset. The secondary retainer has a ring and two secondary retainer arms located axially rearward of the ring.
