Carabiners have a gate that is movable between a closed position and an open position, and a locking member that prevents opening of the gate when the gate is in the closed position and the locking member is in a locked position. The locking member is biased to the locked position. The locking member is also movable to a retainable unlocked position. Methods of manufacturing such carabiners include configuring a locking member of a carabiner to move between a locked position and a retainable unlocked position, and biasing the locking member to the locked position. Methods of using a carabiner include positioning a locking member in a retainable unlocked position, opening a gate of the carabiner, and allowing the locking member to at least substantially automatically move to a locked position as the gate is closed.

1. A carabiner comprising: a body having a first end and a second end;a gate pivotally attached to the first end of the body and movable between a closed position and an open position, the gate extending from the first end of the body to the second end of the body in the closed position; anda locking member movable between a locked position and a retainable unlocked position, the locking member being biased to the locked position and configured to prevent the gate from opening when the gate is in the closed position and the locking member is in the locked position and to allow the gate to open when the gate is in the closed position and the locking member is in the retainable unlocked position, wherein pivoting the gate relative to the body of the carabiner beyond a threshold angle upon opening the gate causes the locking member to move out of the retainable unlocked position. 2. The carabiner of claim 1, wherein the locking member comprises a locking sleeve concentrically disposed about the gate. 3. The carabiner of claim 2, further comprising a spring member disposed between the gate and the locking sleeve, the spring member biasing the locking sleeve to the locked position. 4. The carabiner of claim 3, wherein the locking sleeve is configured to slide longitudinally along the gate, and wherein the spring member is configured to bias the locking sleeve toward the first end of the body. 5. The carabiner of claim 3, wherein the locking sleeve is configured to slide longitudinally along the gate, and wherein the spring member is configured to bias the locking sleeve toward the second end of the body. 6. The carabiner of claim 3, wherein the spring member comprises a torsion spring. 7. The carabiner of claim 6, further comprising a pin member extending at least partially through the first end of the body and the gate, the gate being pivotally attached to the first end of the body by the pin member, and wherein the pin member comprises a head projecting laterally from the first end of the body. 8. The carabiner of claim 7, wherein a surface of the locking sleeve is configured to abut against the head of the pin member. 9. The carabiner of claim 8, wherein the surface of the locking sleeve is configured to define a notch in the locking sleeve, and wherein the head of the pin member is disposed at least partially within the notch in the locking sleeve when the locking sleeve is in the locked position. 10. The carabiner of claim 9, wherein the surface of the locking sleeve is configured to define another notch in the locking sleeve, and wherein the head of the pin member is disposed at least partially within the another notch in the locking sleeve when the locking sleeve is in the retainable unlocked position. 11. The carabiner of claim 3, wherein the locking sleeve comprises an aperture proximate an end thereof sized and configured to allow at least a portion of the second end of the body to pass therethrough when the aperture is aligned with the at least a portion of the second end of the body. 12. The carabiner of claim 11, wherein the aperture is aligned with the at least a portion of the second end of the body when the locking sleeve is in the retainable unlocked position, and wherein the aperture is not aligned with the at least a portion of the second end of the body when the locking sleeve is in the locked position. 13. The carabiner of claim 12, further comprising at least one feature configured to prevent the locking sleeve from rotating about the gate unless the at least a portion of the second end of the body is disposed at least partially within the aperture. 14. A method of manufacturing a carabiner including a body having a first end and a second end, comprising: pivotally attaching a gate to a first end of a body of a carabiner;configuring the gate and the body of the carabiner to allow the gate to pivot between a closed position and an open position when the gate is pivotally attached to the first end of the body;configuring the gate and the body of the carabiner to cause the gate to extend from the first end of the body to a second end of the body when the gate is in the closed position;attaching a locking member to at least one of the gate and the body of the carabiner;configuring the locking member to move relative to the gate between a locked position and a retainable unlocked position, to prevent the gate from opening when the gate is in the closed position and the locking member is in the locked position, and to allow the gate to open when the gate is in the closed position and the locking member is in the retainable unlocked position;biasing the locking member to the locked position; andconfiguring the locking member such that pivoting the gate relative to the body of the carabiner beyond a threshold angle causes the locking member to move out of the retainable unlocked position. 15. The method of claim 14, wherein attaching a locking member to at least one of the gate and the body of the carabiner comprises positioning the locking member concentrically about the gate. 16. The method of claim 15, wherein biasing the locking member to the locked position comprises positioning a spring member between the gate and the locking member and configuring the spring member to act on the locking member. 17. The method of claim 16, further comprising configuring the locking member and the gate to allow the locking member to slide longitudinally along the gate, and further comprising configuring the spring member to force the locking member toward the first end of the body. 18. The method of claim 16, further comprising configuring the locking member and the gate to allow the locking member to slide longitudinally along the gate, and further comprising configuring the spring member to force the locking member toward the second end of the body. 19. The method of claim 14, wherein pivotally attaching a gate to a first end of a body of a carabiner comprises attaching the gate to the first end of the body with a pin member extending at least partially through the first end of the body and the gate. 20. The method of claim 19, further comprising providing a head on the pin member and configuring the head to project laterally from the first end of the body. 21. The method of claim 20, further comprising configuring a surface of the locking member to abut against the head of the pin member. 22. The method of claim 21, further comprising: defining a notch in the surface of the locking member; andconfiguring the locking member and the pin member to cause the head of the pin member to be disposed at least partially within the notch in the surface of the locking member when the locking member is in the locked position. 23. The method of claim 22, further comprising: defining another notch in the surface of the locking member; andconfiguring the locking member and the pin member to cause the head of the pin member to be disposed at least partially within the another notch in the surface of the locking member when the locking member is in the retainable unlocked position.
