1. A karabiner comprising a fixed C-shaped body having a first end shaped as a securing part and a second end for articulation
of a gate movable around a pivoting spindle between a closed position and an open position, said gate comprising:
a latching part situated opposite the pivoting spindle to operate in conjunction with the securing part in the closed position,
a return spring to return the gate to the closed position,
a locking ring fitted coaxially around the gate and having a shorter length than that of the gate, said ring being movable
between a first locked position blocking the gate in the closed position and a second unlocked position enabling the gate
to be moved to the open position, and
a lock-bolt able to block the ring positively in said first locked position, wherein the lock-bolt is placed on the movable
gate and the locking ring is slidingly mounted on the gate between the first and second positions, said ring comprising a
hole for receiving the lock-bolt at the end of the translational travel to the first locked position to constitute both a
mechanical blocking device of the ring and a first visual indicator indicating the locked state, and wherein the lock-bolt
comprises a telescopic pin fitted in a hole of the gate with a compression spring fitted therebetween, the pin having a colored
surface to form said first visual indicator in the locked state.
