An adapter (1) provides a safety gripper system comprising an object housing for secure human-robot interaction. To this end, the adapter (1) has two protective covers (6) which at least partially cover a gripped object (4) and are big enough to shield the object (4). The associated gripper module (2) is firmly installed in the adapter (1) in a first embodiment and can be flexibly exchanged by means of a gripper-change receiving element in a second embodiment. In the closed position, the protective covers (5, 6) protect the people from sharp-edged objects (4) gripped by the gripper module (2), which objects could otherwise lead to injury of the people present in the working space. Owing to the device, sharp-edged or pointed objects (4) can thus also be safely transported by the robot. The protective cover further offers the advantage that objects (4) which are not held securely by the gripper module (2) and slide out of same while the robot is moving, for example, because of centrifugal forces, can be caught.
