A gripper for industrial manipulators includes: at least two jaws one of which being movable allowing it to be opened and closed; and a gripper body. A first gripper body portion housing an actuator device and a second portion supporting the jaws and at least one pin element, defining a pivot axis of the movable jaw, or a pivot axis of at least one transmission element operatively interposed between the at least one movable jaw and the actuator device. The gripper arranged so that the pin element also acts as a locking pin to firmly lock together the first and second portions of the gripper body in assembled condition. The pin element having a circumferential groove which allows a snap coupling of the first portion and the second portion of the gripper body: an elastic element separating them and engaging the edge of one of the two in the groove.
