and an outer sleeve having a first end, a second end, and a center axis that is parallel to the center axis of the inner sleeve, wherein the outer sleeve has an inner surface contoured to position the outer sleeve relative to an actuating collar of the female quick connect fitting, wherein the actuating collar has an engaged position and a disengaged position. ## Claims ### Claim 1 A quick connect spray shield apparatus, the apparatus comprising: an inner sleeve having a first end, a second end, and a center axis that is parallel to an axis from the first end to the second end, wherein: the inner sleeve has an inner surface that is contoured to position the inner sleeve relative to the outer surface of a female quick connect fitting, and the inner sleeve is positioned away from an actuating collar of the female quick connect fitting such that the actuating collar is operable to move between the engaged position and the disengaged position without interference from the inner sleeve; an outer sleeve having (i) a first end, (ii) a second end, and (iii) a center axis that corresponds to the center axis of the inner sleeve, wherein: the first end of the outer sleeve is operable to receive a male quick connect fitting that mates with the female quick connect fitting, the outer sleeve has an inner surface contoured to position the outer sleeve relative to the actuating collar of the female quick connect fitting, the actuating collar has an engaged position and a disengaged position, and the outer sleeve further comprises a viewing window that is operable to align with an indicator of the inner sleeve when the actuating collar is in the engaged position, and wherein the indicator is operable to lock into the viewing window when the viewing window is aligned with the indicator. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the outer sleeve further comprises: a plurality of flanges protruding from the inner surface of the outer sleeve, wherein: the plurality of flanges translate a force exerted on the outer sleeve to the actuating collar, the force is exerted in a direction parallel to the center axis of the outer sleeve, and the position of the actuating collar is maintained. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the indicator is disposed upon a lever located on the outer surface of the inner sleeve. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the lever is biased toward a locked position, and wherein the lever is moveable to an unlocked position by movement toward the center axis of the inner sleeve. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the indicator unlocks from the viewing window by movement of the lever toward the center axis of the inner sleeve. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the outer sleeve has a flexible portion that translates force to the lever of the inner sleeve, wherein the force is toward the center axis of the outer sleeve and wherein the flexible portion is aligned with the lever of the inner sleeve. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the female quick connect fitting transmits fluid in a direction parallel to the center axis of the inner sleeve and the center axis of the outer sleeve. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the outer sleeve extends beyond the actuating collar, wherein the outer sleeve deflects the fluid upon a leak from the female quick connect fitting. ### Claim 9 A quick connect spray shield apparatus, the apparatus comprising: an inner sleeve having a first end, a second end, and a center axis that is parallel to an axis from the first end to the second end, wherein the inner sleeve has an inner surface that is contoured to position the inner sleeve relative to the outer surface of a female quick connect fitting, wherein the inner sleeve is positioned away from an actuating collar of the female quick connect fitting such that the actuating collar moves between the engaged position and the disengaged position without interference from the inner sleeve; an outer sleeve having (i) a first end, (ii) a second end, and (iii) a center axis that corresponds to the center axis of the inner sleeve, wherein the outer sleeve has an inner surface contoured to position the outer sleeve relative to the actuating collar of the female quick connect fitting, wherein the actuating collar has an engaged position and a disengaged position; a plurality of flanges protruding from the inner surface of the outer sleeve, wherein the plurality of flanges translate a force exerted on the outer sleeve to the actuating collar, wherein the force is exerted in a direction parallel to the center axis of the outer sleeve; an indicator disposed upon a lever located on the outer surface of the inner sleeve, wherein the lever is biased toward a locked position, and wherein the lever is moveable to an unlocked position by movement toward the center axis of the inner sleeve; a viewing window disposed upon the outer sleeve that receives the indicator of the inner sleeve when the actuating collar is in the engaged position, wherein the indicator locks into the viewing window when the viewing window is received by the indicator, and wherein the outer sleeve is impeded from moving when the indicator is locked into the viewing window; a flexible portion disposed on the outer sleeve that translates force to the lever of the inner sleeve, wherein the force is toward the center axis of the outer sleeve and wherein the flexible portion is aligned with the lever of the inner sleeve, and wherein the force on the lever unlocks the indicator from the viewing window; and wherein the outer sleeve is able to slide parallel to the center axis of the outer sleeve when the indicator is unlocked from the viewing window when the force is exerted in a direction parallel to the center axis of the outer sleeve. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the first end of the outer sleeve receives a male quick connect fitting that mates with the female quick connect fitting. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein the female quick connect fitting transmits fluid in a direction parallel to the center axis of the inner sleeve and the center axis of the outer sleeve.
