The gripper comprises a jack body, a gripper head connected to the body, rotary fingers carried by the head, a jack rod and a manoeuvring component securely fastened to the rod and capable of causing the fingers to pivot. The gripper head 2 can move parallel to the rod 5 between a contact position and a position in which it is moved slightly away from the body 1. The latter further comprises a control slide valve 31 which can move in a cavity 12 and is composed of a rod upon which there are mounted three rings 32, 33, 34 defining four chambers by means of which fluid connections are established. The slide valve 31 only passes into the top position when the gripper has actually grasped a component. <IMAGE>
