Abstract: A belt buckle having an insertion part having at least a belt opening for guiding a belt and an insertion appendage extending in a direction of insertion with holding catches at both sides projecting in the perpendicular direction, and a receiving part having a basic body with at least a belt opening for guiding a belt and with an insertion opening, beginning at an inserting side of the basic body for inserting the insertion appendage of the insertion part in the direction of insertion, and with latches pivotally mounted to the basic body, which in the locking position in the inserted state of the receiving part and the insertion part cooperate with holding catches and retain the insertion appendage in the insertion opening of the receiving part.

Abstract: A karabiner is provided having a hoop and a closing part mounted pivotally via a pivoting axle to the hoop at the insertion opening of the hoop. At least one blocking element is pivotally mounted to the closing part via a blocking element—pivot axle, with the blocking element, at least in a closed position of the closing part, blocking the closing part in its closed position from pivoting towards its opened position and in at least one released position allows the closing part to pivot towards its opened position. The blocking element is pivoted around the blocking element—pivot axle for pivoting it from the blocking position towards the released position in the same rotary direction around the blocking element—pivot axle as the closing part for pivoting the closing part out of the closed position towards its opened position around the closing part—pivot axle.
