A quick-action closure for the end fitting of a safety belt, whereby the quick-action closure includes an insertion tongue which can be inserted into a closure housing and which can be locked therein by means of a locking element disposed in a mobile manner between a locking position and a release position, and whereby the locking element can be transferred from its locking position into its release position by means of an actuating element which can be inserted into the closure housing. A safety element (21) is disposed in the closure housing (11) mounted at its center of gravity (35) rotatable between a safety position and a rest position, the safety element in its safety position fixing the locking element (20) in its locking position and, in its rest position, releasing the locking element (20), whereby the safety element (21) is held in its safety position by the action of a spring (25).

1. A quick-action closure for an end fitting of a safety belt, the quick-action closure comprising: a closure housing,an insertion tongue configured for insertion into the closure housing along an insertion path,a locking element disposed in the closure housing and movable between a locking position and a release position, the locking element locking the insertion tongue in the closure housing when the locking element is in the locking position,a safety element mounted in the closure housing and rotatable about an axis of rotation between a safety position and a rest position, the safety element in the safety position fixing the locking element in the locking position and, in the rest position, releasing the locking element, the axis of rotation extending through a center of gravity of a safety element arrangement that includes at least the safety element,a spring urging the safety element toward the safety position, andan actuating element configured to be inserted into the closure housing, the actuating element being dimensioned to abut the locking element upon insertion of the actuating element into the closure housing and to move the locking element from the locking position to the release position. 2. The quick-action closure according to claim 1, wherein the spring is further tensioned by the insertion of the insertion tongue into the closure housing. 3. The quick-action closure according to claim 1, wherein the actuating element is dimensioned to engage the safety element upon insertion of the actuating element into the closure housing and to move the safety element from the safety position to the rest position and wherein the safety element has a retaining stop fixing the locking element in the safety position, and an actuating stop for the actuating element. 4. The quick-action closure according to claim 3, wherein the actuating stop has a radial cutout configured to be engaged by the actuating element. 5. The quick-action closure according to claim 4, wherein the safety element has a mass balance compensating for the radial cutout. 6. The quick-action closure according to claim 5, wherein the mass balance of the safety element is formed by a counter-cutout which is generally rotation-symmetric to the radial cutout in the safety element with respect to the axis of rotation. 7. The quick-action closure according to claim 3, wherein the actuating element is a fork-shaped tool with first and second forks, the first fork being oriented towards the actuating stop of the safety element when the actuating element is inserted into the closure housing and the second fork acting on the locking element in a direction from the locking position into the release position. 8. The quick-action closure according to claim 7, wherein a path of movement of the forks of the actuating element is disposed on different sides of the axis of rotation of the safety element and that the rotational directions of the movement of the safety element from the safety position into its rest position and of the locking element from the locking position into the release position are oriented in an opposing manner. 9. The quick-action closure according to claim 7, wherein the first and second forks of the actuating element have a different length such that, when the actuating element is inserted into the closure housing, the first fork first acts on the actuating stop of the safety element and rotates the safety element into the rest position and then the second fork takes up the locking element and transfers it into the release position. 10. The quick-action closure according to claim 1 wherein the closure housing is generally U-shaped with two housing plates laterally bounding the insertion path for the insertion tongue and a web connecting the housing plates, and that the insertion tongue, on its side facing away from the web, has a locking recess for the engagement of the locking element and, with its rear side lying opposite the locking recess, rests in the locking position against the web of the closure housing. 11. The quick-action closure according to claim 1, further comprising a safety belt and a cable configured to lead to an end-fitting tightener or to a holder or to a belt strap, wherein the insertion tongue forms the end fitting connected to the safety belt and wherein the closure housing is connected to the cable. 12. The quick-action closure according to claim 1, wherein the locking element is disposed with swiveling mobility about a swivel axis perpendicular to lateral housing plates of the closure housing. 13. The quick-action closure according to claim 1 wherein the locking element is disposed with swiveling mobility in a longitudinal direction of the closure in a plane parallel to lateral housing plates of the closure housing. 14. The quick-action closure according to claim 1, wherein the safety element arrangement further includes the spring. 15. A quick-action closure for an end fitting of a safety belt, the quick-action closure comprising: a closure housing,an insertion tongue configured for insertion into the closure housing along an insertion path,a locking element disposed in the closure housing and movable between a locking position and a release position, the locking element locking the insertion tongue in the closure housing when the locking element is in the locking position,a safety element mounted in the closure housing and rotatable about an axis of rotation between a safety position and a rest position, the safety element in the safety position fixing the locking element in the locking position and, in the rest position, releasing the locking element, the axis of rotation extending through a center of gravity of a safety element arrangement that includes at least the safety element,a spring urging the safety element toward the safety position, and an actuating element configured to be inserted into the closure housing, the actuating element being dimensioned to engage the locking element upon insertion of the actuating element into the closure housing and to move the locking element from the locking position to the release position, wherein the spring is a torsion spring formed with first and second free ends, the first end extending into the insertion path of the insertion tongue and the second end acts on the safety element. 16. The quick-action closure according to claim 15, wherein the safety element comprises a channel for accommodating the second end of the torsion spring.
