The present invention relates to a connecting device (5, 5′) for connecting at least two pipe parts, wherein the connecting device is connected at least in portions to a first pipe part, and a detachable connection to at least one connecting element (3, 4) operatively connected to a second pipe part (1) can be produced by means of said connecting device. The connecting device comprises at least one locking ring (7, 7′) with at least two elastically movable catch tabs (11 11′) protruding in a radially inward direction of the locking ring, and at least one actuator ring (9, 9′) for moving the catch tabs out of at least one locking position, in which at least one of the catch tabs is engaged in the connecting element, into at least one unlocking position in which the engagement is detached, and vice versa. The respective catch tab is resiliently mounted at a first end on the locking ring via at least one catch arm (21, 21′), and a second end of the catch tab opposite from the first end is freely movable. In addition, at least one guide element (13, 13′) is arranged in the area of the second end of the respective catch tab and the respective guide element is guided in at least one slot (15, 15′) comprised by the actuator ring, in such a manner that the catch tab can be forced into the locking position by a spring force built up by the catch arm, and can be forced out of the locking position against the spring force and into the unlocking position by means of a movement of the actuator ring relative to the locking ring and/or the locking ring relative to the actuator ring. The invention further relates to a connecting system comprising such a connecting device. |

1. A connecting device (5, 5′) for connecting at least two pipe parts, wherein the connecting device (5, 5′) is connected at least sectionwise to a first pipe part, and a detachable connection to at least one connecting element (3, 4) operatively connected to a second pipe part (1) can be produced by means of said connecting device (5, 5′), the connecting device (5, 5′) comprises at least one locking ring (7, 7′) with at least two elastically movable catch tabs (11, 11′) protruding in a radially inward direction of the locking ring (7, 7′), and at least one actuator ring (9, 9′) for moving the catch tabs (11, 11′) out of at least one locking position, in which at least one of the catch tabs (11, 11′) is engaged in the connecting element (3), into at least one unlocking position in which the engagement is detached, and vice versa, wherein the respective catch tab (11, 11′) is resiliently mounted at a first end on the locking ring (7, 7′) via at least one catch arm (21, 21′), and a second end of the catch tab (11, 11′) opposite from the first end is freely movable, characterized in that at least one guide element (13, 13′) is provided in the vicinity of the second end of the respective catch tab (11, 11′) and that the respective guide element (13, 13′) is guided in at least one slot (15, 15′) comprised by the actuator ring (9, 9′), in such a manner that the catch tab (11, 11′) can be forced into the locking position by the spring force built up by the catch arm (21, 21′) and can be forced out of the locking position against said spring force and into the unlocking position by means of a movement of the actuator ring (9, 9′) relative to the locking ring (7, 7′) and/or of the locking ring (7, 7′) relative to the actuator ring (9, 9′). |
