Abstract: A carabiner has a hock body with a foot section, a back section connected to the foot section, a top section connected to the back section and bent like a hook in the direction of the foot section, a lug arranged at the foot section, and a snap tongue pivotally linked to the foot section and having the form of a wire which is bent to a U-shackle and is made of spring steel. The U-limbs of the U-shackle have different lengths and the ends of the U-limbs are bent inwardly and are inserted into bearing openings which are arranged in the region of the foot section such that the snap tongue, in the closed position of the carabiner, contacts spring loaded the inner surface of the top section which is bent in the direction of the foot section. A retaining element prevents the accidental displacement of the snap tongue out of its contact position against the inner surface of the end portion of the top section bent into the direction of the foot section.
