Carabiners with multi mode locking sleeves, methods of manufacturing such carabiners, and methods of using such carabiners

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;
• and
• configuring 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.
