Safety securing device and securing assembly comprising such a device

1. A safety securing device comprising a first carabiner and a second carabiner configured to receive a securing element, each of the first and second carabiners comprising:

a hook provided with an opening, said opening configured to receive said securing element,

said hook having a receiving zone configured to contain said securing element;

a gate rotatably mounted to the hook and rotatable around a rotation axis, said gate having two arms configured to receive said securing element, wherein said gate is configured to rotate into a housing configuration, said housing configuration comprises said securing element being located between said two arms and said receiving zone;

wherein at least one of said two arms is configured for closing said opening when said gate is positioned in said housing configuration;

a locking part mounted to said hook and coupled to said gate; said locking part configured to move with respect to said hook between a locked position and an unlocked position, said locking part being coupled to a constraint spring; said constraint spring configured to activate said locking part when said gate closes said opening,

said first carabiner connected to said second carabiner by a first cable connecting the first carabiner gate to said second carabiner locking part,

wherein when said first carabiner gate is moved into the housing configuration of said first carabiner gate, said first carabiner gate activates the first cable to cause deactivation of the second carabiner locking part,

a first sheath coupled between the hook of the first carabiner and the hook of the second carabiner, said first cable being configured to slide in said first sheath,

said first carabiner connected to said second carabiner by a second cable connecting the second carabiner gate to said first carabiner locking part,

wherein when said second carabiner gate is moved into the housing configuration of said second carabiner gate, said second carabiner gate activates the second cable to cause deactivation of said first carabiner locking part,

a second sheath coupled between the hook of the first carabiner and the hook of the second carabiner, said second cable being configured to slide in said second sheath.

2. The safety securing device according to claim 1 , wherein the first carabiner gate comprises a first carabiner first tooth, and wherein the constraint spring of the first carabiner is arranged to put said first carabiner locking part in engagement with said first carabiner first tooth when said first carabiner gate is in the housing configuration of said first carabiner gate and when the second carabiner gate is in a receiving configuration of said second carabiner gate, so as to activate said first carabiner locking part; and

wherein the second carabiner gate comprises a second carabiner first tooth, and wherein the constraint spring of the second carabiner is arranged to put said second carabiner locking part in engagement with said second carabiner first tooth when said second carabiner gate is in the housing configuration of said second carabiner gate, so as to activate said second carabiner locking part.

3. The safety securing device according to claim 1 , wherein the first carabiner comprises an additional first carabiner locking part configured for locking the first carabiner gate, said additional first carabiner locking part being mounted so as to be able to move with respect to the first carabiner hook between a first carabiner locking position and first carabiner unlocking position, said additional first carabiner locking part being coupled to an additional first carabiner constraint spring arranged so as to activate said additional first carabiner locking part when the first carabiner gate is closed, said additional first carabiner locking part comprising first carabiner abutment zone for deactivating said additional first carabiner locking part by action of a user, and wherein the second carabiner comprises an additional second carabiner locking part configured for locking the second carabiner gate, said additional second carabiner locking part being mounted so as to be able to move with respect to the second carabiner hook between a second carabiner locking position and second carabiner unlocking position, said additional second carabiner locking part being coupled to an additional second carabiner constraint spring arranged so as to activate said additional second carabiner locking part when the second carabiner gate is closed, said additional second carabiner locking part comprising a second carabiner abutment zone for deactivating said additional second carabiner locking part by action of the user.

4. The safety securing device according to claim 3 , wherein the first carabiner gate comprises a first carabiner second tooth, the additional first carabiner locking part being rotatably mounted with respect to the first carabiner hook, said additional first carabiner constraint spring, being arranged to put said additional first carabiner locking part in engagement with said first carabiner second tooth when the first carabiner gate is in the housing configuration of the first carabiner gate, so as to activate said additional first carabiner locking part, and wherein the second carabiner gate comprises a second carabiner second tooth, the additional second carabiner locking part being rotatably mounted with respect to the second carabiner hook, said additional second carabiner constraint spring, being arranged to put said additional second carabiner locking part in engagement with said second carabiner second tooth when the second carabiner gate is in the housing configuration of the second carabiner gate, so as to activate said additional second carabiner locking part.
