US Patent 10092784 Safety securing device and securing assembly comprising such a device

A safety securing device has two carabiners intended to receive a securing element. Each of the carabiners includes a hook provided with an opening. A detection device is activated upon insertion of the securing element into the hook. A closure door and a device for locking the door are coupled to a stressing device arranged to activate the locking device when the door is closed. The carabiners are interconnected by a transmission device that connects the detection device of one carabiner to the locking device of the other carabiner. The activation of the detection device of one of the carabiners triggers the deactivation of the locking device of the other carabiner.
