Abstract

A retainer including a first section including a first male connector and a first female connector, a second section completely removable from the first section, the second section including a second male connector and a second female connector, a first end, a second end, a radially inward facing surface including a radially inward extending rib, and a radially outward facing surface, wherein the first male connector is arranged to engage the second female connector and the second male connector is arranged to engage the first female connector to lock the first section to the second section.

Claims (65)

1 . A retainer for a fluid connection assembly, comprising:

a first section including a first male connector and a first female connector;

a second section completely removable from the first section, the second section comprising a second male connector and a second female connector;

a first end;

a second end;

a radially inward facing surface including a radially inward extending rib; and

a radially outward facing surface;

wherein:

the first male connector is arranged to engage the second female connector and the second male connector is arranged to engage the first female connector to lock the first section to the second section;

at least one of the first male connector and the second male connector comprises a first recess extending radially inward from the radially outward facing surface and a first projection extending radially outward from the first recess; and

the first recess increases in width in a first circumferential direction.

2 . The retainer as recited in claim 1 , wherein the first recess is arranged axially between and spaced apart from the first end and the second end.

3 . The retainer as recited in claim 2 , wherein the first recess forms a first axial surface and a second axial surface.

4 . The retainer as recited in claim 3 , wherein the first projection is arranged axially between and spaced apart from the first axial surface and the second axial surface.

5 . The retainer as recited in claim 1 , wherein the first projection comprises a tapered surface that extends radially outward in a second circumferential direction, opposite the first circumferential direction.

6 . The retainer as recited in claim 1 , wherein the at least one rib comprises:

a first axial surface extending radially inward from the radially inward facing surface;

a second axial surface extending radially inward from the radially inward facing surface; and

a convex surface connecting the first axial surface with the second axis surface.

7 . The retainer as recited in claim 1 , wherein at least one of the first female connector and the second female connector comprises:

a circumferential end; and

a tab extending in a circumferential direction from the circumferential end, the tab including a through-hole.

8 . The retainer as recited in claim 7 , wherein an axial distance between the first end and the second end is greater than the width of the tab.

9 . The retainer as recited in claim 1 , wherein at least one of the first male connector and the second male connector comprises:

a first circumferential end; and

a first tab extending in a first circumferential direction from the first circumferential end, wherein the first tab includes a second projection, the second projection extending radially outward.

10 . The retainer as recited in claim 9 , wherein an axial distance between the first end and the second end is greater than the width of the first tab.

11 . The retainer as recited in claim 9 , wherein the at least one of the first male connector and the second male connector further comprises a first protrusion extending in the first circumferential direction from the first circumferential end, wherein a radial space is formed between the first tab and the first protrusion.

12 . The retainer as recited in claim 11 , wherein at least one of the first female connector and the second female connector comprises a second protrusion operatively arranged to engage the radial space.

13 . The retainer as recited in claim 9 , wherein at least one of the first female connector and the second female connector comprises:

a second circumferential end; and

a second tab extending radially outward from the second circumferential end, wherein the second tab includes a through-hole.

14 . The retainer as recited in claim 13 , wherein the at least one of the first female connector and the second female connector further comprises a second recess, the second recess extending radially inward and axially aligned with the through-hole.

15 . The retainer as recited in claim 1 , wherein the at least one rib is arranged axially between and spaced apart from the first end and the second end.

16 . The retainer as recited in claim 1 , wherein the at least one rib comprises:

a first rib aligned with the first end; and

a second rib aligned with the second end, the second rib axially spaced apart from the first rib.

17 . The retainer as recited in claim 1 , wherein at least one of the first male connector and the second male connector comprises:

a second recess extending from the second end partially toward the first end in an axial direction, the second recess forming a first plurality of teeth;

a first circumferential end; and

a protrusion extending from the first circumferential end in a first circumferential direction.

18 . The retainer as recited in claim 17 , wherein at least one of the first female connector and the second female connector comprises:

a second circumferential end;

a tab extending from the second circumferential end in a second circumferential direction, opposite the first circumferential direction, the tab forming a second plurality of teeth engageable with the first plurality of teeth; and

a radial space arranged between the tab and the radially inward facing surface, wherein the protrusion is operatively arranged to engage the radial space.

19 . A retainer for a fluid connection assembly, comprising:

a first section including a first male connector and a first female connector;

a second section completely removable from the first section, the second section comprising a second male connector and a second female connector;

a first end;

a second end;

a radially inward facing surface including a radially inward extending rib; and

a radially outward facing surface;

wherein:

the first male connector is arranged to engage the second female connector and the second male connector is arranged to engage the first female connector to lock the first section to the second section; and

at least one of the first male connector and the second male connector comprises a first circumferential end, and a first tab extending in a first circumferential direction from the first circumferential end, wherein the first tab includes a radially outward extending projection.

20 . A retainer for a fluid connection assembly, comprising:

a first section including a first male connector and a first female connector;

a second section completely removable from the first section, the second section comprising a second male connector and a second female connector;

a first end;

a second end;

a radially inward facing surface including a radially inward extending rib; and

a radially outward facing surface;

wherein:

the first male connector is arranged to engage the second female connector and the second male connector is arranged to engage the first female connector to lock the first section to the second section; and

at least one of the first female connector and the second female connector comprises a circumferential end and a tab extending in a circumferential direction from the circumferential end, the tab including a radially extending through-hole.
