Gripper with interchangeable head comprising:

• a body (1) defining a longitudinal axis, comprising a first end (1a) intended to be fitted into a nut (2) and a second, free end (1b) provided with sectors (11) capable of elastic deformation in a radial direction and intended to receive a removable head,
• a thrust pin (3) mounted to slide along said longitudinal axis inside said body (1), in a first direction under the effect of a driving force transmitted through the nut by a kinematic connection means and in a second direction under the effect of a spring member (7),
• a plurality of lugs (4) mounted integrally and in a regular angular arrangement on the thrust pin (3) and protruding radially from the surface of said thrust pin through the body (1) of the gripper, wherein said lugs (4) are fixedly arranged in a longitudinal and radial position on the thrust pin (4) by a fixing means (9).
