A coupling part for a fluid coupling device, especially a hose coupling, which has a looking device switchable between two positions. The locking device has locking elements mounted on a base body, and a socket-shaped actuating element that interacts with the locking elements. The coupling part is switchable between a retaining and releasing positions by an axial releasing movement of the actuating element. In the retaining position, the locking elements hold the counterpart of the coupling, e.g. a hose stem, to prevents it from being pulled out and, in the releasing position, the locking elements release the same in order to disengage the coupling. The actuating element can be moved from the retaining position into a locking position, prohibiting a releasing movement, by rotating the actuating element in a limited manner around the longitudinal axis of the coupling. As a result, the coupling is prevented from being unintentionally disengaged.

What is claimed is: 1. A coupling part for a fluid coupling device, the coupling part being connectable and releasable in an axial direction with a corresponding part of a hose coupling, the coupling part comprising: a switchable locking device for locking the coupling part to a corresponding hose coupling part in a coupling position in an extraction-prevented manner; the locking device comprising at least one locking element comprising a resilient insert body having a cam section actable on a corresponding hose coupling part, and an actuating element cooperating with the locking element, wherein coupling of the coupling part to a corresponding hose coupling part is achieved by axial movement of the coupling part and the hose coupling part together to a retaining position, wherein the actuating element is moveable in the axial direction between the retaining position and a release position such that the locking device is switched between a locking configuration and a release configuration, wherein the resilient insert body can be blocked in a locking position preventing release of the coupling parts from the locking configuration by an additional movement of the actuating element, and wherein the actuating element or a main body of the coupling part has at least one substantially L-shaped recess, in which a leg at right angles to the release direction forms a stop and a portion in the release direction forms a linear guide for a counterelement of the main body or actuating element. 2. The coupling part according to claim 1, wherein the coupling part is brought into the retaining position with the corresponding hose coupling part without at least one of actuation and movement of the actuating element. 3. The coupling part according to claim 1, wherein the actuating element is arranged in a movable manner on the coupling part relative to a main body of the coupling part and is pretensioned in its retaining position, and wherein the actuating element is movable in a release direction for the release of the locking device from the retaining position into the release position and can be moved into the locking position by movement in a locking direction perpendicular to the release direction. 4. The coupling part according to claim 3, wherein the movement in the release direction is a displacement in a longitudinal direction of the main body and the movement in the locking direction is a rotation of the actuating element about a longitudinal axis of the main body. 5. The coupling part according to claim 1, wherein the actuating element is an actuating sleeve, which embraces a main body of the coupling part. 6. The coupling part according to claim 1, wherein the actuating element has at least one stop on its inside facing a main body of the coupling part, wherein the at least one stop is oriented perpendicular to the release direction and extends transversely to the release direction over a limited stop length and cooperates with a counterstop of the main body in such a way that the actuating element, starting from the retaining position and whilst bypassing the stop, is movable in the release direction into the release position and, starting from the locking position, is blocked by a counterelement striking against the stop in the release direction. 7. The coupling pan according to claim 1, wherein a main body of the coupling part, on its outside facing the actuating element, has at least one stop perpendicular to the release direction over a limited stop length which cooperates with a counterstop of the actuating element in such a way that the actuating element, starting from the retaining position and whilst bypassing the stop, is movable in the release direction to the release position and, starting from the locking position, is blocked by the counterstop striking against the stop in the release direction. 8. The coupling part according to claim 6, wherein at least one of the stop and the counterelement is constructed in one piece with at least one of the actuating element and the main body. 9. The coupling part according to claim 1, wherein several stops and counterelements are distributed about the circumference of the coupling part. 10.
