A one-piece container gripper for suspending containers from a container region beneath a container mouth has segments, a locking portion, and a spring portion. On a front side of the container gripper, the segments define a container mount between them. The spring portion exerts a closing force pre-stressing the segments, thus urging the container mount to close. The segments can be moved apart against a spring-exerted closing force to open the gripper. The locking portion, which is integral with the container gripper, moves resiliently between a position that locks the gripper and a position that unlocks it.
