    • The connector assembly includes a housing with an open bore which extends along an axis from an open first end to an open second end. The housing further includes a plurality of fingers that are spaced circumferentially from one another and are deflectable in a radial direction. At least one of the fingers has a plurality of teeth that are spaced axially from one another and extend into the open bore of said housing for biting into the first tube to resist pull out of the first tube from the open bore. Each of the teeth also extends by a height to a leading edge of an engagement surface which also includes an angled portion that extends at an angle relative to the axis. The axially spaced teeth have at least one of differing heights and differing angles of the angled portions.
    • 连接器组件包括具有开口孔的壳体,该开口孔沿着轴线从开放的第一端部延伸到打开的第二端部。 壳体还包括多个彼此周向间隔开并且沿径向可偏转的指状物。 指状物中的至少一个具有多个彼此轴向间隔开并且延伸到所述壳体的开孔中的齿,用于咬入第一管以阻止从开口孔拉出第一管。 每个齿还延伸到接合表面的前缘的高度,该接合表面还包括相对于轴线成一定角度延伸的倾斜部分。 轴向隔开的齿具有成角度部分的不同高度和不同角度中的至少一个。
