The carabiner comprises a body associated with a gate able to rotate on a first end of the body between a closed position and an open position of the carabiner. A confinement element is configured to form a first stop and a second stop salient from the body. The confinement element is fitted removable with respect to the body. The confinement element is fixed to the body by a first fastener and a second fastener. A joining part connects the first fastener to the second fastener to define the space separating the first stop and the second stop. The joining part is pressed against the body. The body, the gate and the joining part define a carabiner with a single central ring.
