a second end; a first through-bore; a first radially outward facing surface including at least one aperture extending from the first radially outward facing surface to the first through-bore; and at least one engaging element arranged in the at least one aperture; a collar connected to the connector body, the collar including: a radially inward facing surface engaged with the first radially outward facing surface and including at least one pocket extending radially outward therefrom; and a second radially outward facing surface; and a detent operatively arranged to non-rotatably connect the collar and the connector body. ### Claim 2 (depends on 1) The fluid connection assembly as recited in claim 1, wherein: in an unlocked state, the at least one engaging element is engaged with the at least one pocket; and in the locked state, the at least one engaging element is engaged with the radially inward facing surface and extends into the first through-bore. ### Claim 3 (depends on 1) The fluid connection assembly as recited in claim 1, wherein the at least one pocket increases in depth in a first circumferential direction. ### Claim 4 (depends on 1) The fluid connection assembly as recited in claim 1, wherein the at least one aperture is frusto-conical. ### Claim 5 (depends on 1) The fluid connection assembly as recited in claim 1, wherein: the connector body further comprises a recess in the first radially outward facing surface; the collar further comprises a second through-bore extending from the radially inward facing surface to the second radially outward facing surface; and the detent is slidably arranged in the second through-bore. ### Claim 6 (depends on 5) The fluid connection assembly as recited in claim 5, wherein the detent comprises: a first section operatively arranged to engage the recess; a second section; and a biasing element operatively arranged to bias the first and second sections radially inward. ### Claim 7 (depends on 6) The fluid connection assembly as recited in claim 6, wherein: in an unlocked state, the second section protrudes radially outward from the second radially outward facing surface; and in a locked state, the second section does not protrude radially outward from the second radially outward facing surface. ### Claim 8 (depends on 6) The fluid connection assembly as recited in claim 6, wherein: in an unlocked state, the first section is engaged with the radially outward facing surface and the collar is rotatable with respect to the connector body; and in a locked state, the first section is engaged with the recess and the collar and the connector body are non-rotatably connected. ### Claim 9 (depends on 5) The fluid connection assembly as recited in claim 5, wherein the connector body further comprises a groove arranged in the first radially outward facing surface and at least partially aligned with the recess. ### Claim 10 (depends on 9) The fluid connection assembly as recited in claim 9, wherein the groove comprises a first depth and the recess comprises a second depth, the first depth being greater than the second depth. ### Claim 11 (depends on 5) The fluid connection assembly as recited in claim 5, wherein the second through-bore comprises a counter-bore extending radially outward from the radially inward facing surface. ### Claim 12 (depends on 1) The fluid connection assembly as recited in claim 1, further comprising a retaining ring operatively arranged in a groove of the connector body to rotatably connect the collar with the connector body. ### Claim 13 (depends on 1) The fluid connection assembly as recited in claim 1, further comprising a tube including a shoulder, wherein the at least one engaging element is arranged to engage the shoulder to secure the tube to the connector body. ### Claim 14 (depends on 1) The fluid connection assembly as recited in claim 1, wherein: in an unlocked state, the at least one engaging element is engaged with the at least one pocket; and, in the locked state, the at least one engaging element is engaged with the radially inward facing surface and extends into the first through-bore. ### Claim 15 A fluid connection assembly, comprising: a connector body, including: a first end; a second end; a first through-bore; a first radially outward facing surface including at least one aperture extending from the first radially outward facing surface to the first through-bore and a recess extending radially inward from the first radially outward facing surface; and at least one engaging element arranged in the at least one aperture; a collar connected to the connector body, the collar including: a radially inward facing surface engaged with the first radially outward facing surface and including at least one pocket extending radially outward therefrom; a second radially outward facing surface; and a second through-bore extending from the radially inward facing surface to the second radially outward facing surface; and a detent slidably arranged in the second through-bore and operatively arranged to engage the recess to non-rotatably connect the collar and the connector body. ### Claim 16 (depends on 14) The fluid connection assembly as recited in claim 14, wherein the detent is biased radially inward. ### Claim 17 (depends on 15) The fluid connection assembly as recited in claim 15, wherein: in an unlocked state, the detent protrudes radially outward from the second radially outward facing surface; and in a locked state, the detent does not protrude radially outward from the second radially outward facing surface. ### Claim 18 (depends on 14) The fluid connection assembly as recited in claim 14, wherein: in an unlocked state, the detent is engaged with the radially outward facing surface and the collar is rotatable with respect to the connector body; and in a locked state, the detent is engaged with the recess and the collar and the connector body are non-rotatably connected. ### Claim 19 (depends on 14) The fluid connection assembly as recited in claim 14, wherein the connector body further comprises a groove arranged in the first radially outward facing surface and at least partially aligned with the recess. ### Claim 20 A fluid connection assembly, comprising: a connector body, including: a first end; a second end; a first through-bore; a first radially outward facing surface including at least one aperture extending from the first radially outward facing surface to the first through-bore; and at least one engaging element arranged in the at least one aperture; and a collar connected to the connector body, the collar including: a first section; a second section removably connected to the first section; and a radially inward facing surface engaged with the first radially outward facing surface and including at least one pocket, the at least one pocket extending radially outward on the first section and the second section.
