Abstract: Provided herein is a connection tool for connecting to an object a carabiner that has an internal space and a carabiner opening for admitting the object to the internal space. The connection tool includes a support structure and a handle connected to the support structure. The support structure defines a support opening sized and shaped to permit the carabiner to be received and withdrawn from the support structure. The support structure is sized and shaped to hold the carabiner while leaving the carabiner opening unobstructed such that the object can be admitted to and removed from the internal space through the carabiner opening such that the carabiner can be connected to and disconnected from an object not reachable by hand using the tool.

Abstract: A carabiner comprising a body having an opening, a closure movably coupled to the body, the closure being movable to an open position, and to a closed position in which the opening is closed by the closure such that the body and the closure define a closed shape, and an actuator, coupled to the closure and operatively connected to the body, the actuator being configured to cause the closure to move to the closed position in response to loading of the carabiner, and to cause the closure to move from the closed position to the open position in response to unloading of the carabiner.
