1. A venting valve comprising: a securing part and an end member, wherein the securing part and the end member form a monolithic structure;wherein the end member comprises an outer circumferential wall and a disk-shaped valve body arranged at an end of the outer circumferential wall facing away from the securing part, wherein the disk-shaped valve body is connected circumferentially to the outer circumferential wall and extends transverse to a center axis of the circumferential wall, wherein the disk-shaped valve body has an outer end face and an inner side that is extending substantially parallel to the outer end face, wherein the disk-shaped valve body is provided with at least one diametrically extending venting slot penetrating the disk-shaped valve body from the outer end face to the inner side;wherein the securing part has a mounting diameter in a mounted state such that the securing part is radially elastically expanded and the radial elastic expansion generates a radial force causing a closure tension acting on the venting slot so as to close the venting slot in the mounted state. 2. The venting valve according to claim 1, wherein the securing part is cylindrical. 3. The venting valve according to claim 1, wherein the securing part has an inner side that is provided with a snap-on profile comprising a radially inwardly projecting portion adapted to be engaged from behind by a rim of an apparatus connector to which the venting valve is attached. 4. The venting valve according to claim 1, comprising a conical member, wherein the securing part is connected by the conical member to the end member. 5. The venting valve according to claim 1, wherein the venting slot extends straight. 6. The venting valve according to claim 1, wherein the venting valve is comprised of a unitary elastomer material. 7. A venting valve comprising: a securing part and an end member, wherein the securing part and the end member form a monolithic structure;wherein the end member comprises an outer circumferential wall and a disk-shaped valve body arranged at an end of the outer circumferential wall facing away from the securing part, wherein the disk-shaped valve body is connected circumferentially to the outer circumferential wall and extends transverse to a center axis of the circumferential wall, wherein the disk-shaped valve body has an outer end face and an inner side that is extending substantially parallel to the outer end face, wherein the disk-shaped valve body is provided with at least one diametrically extending venting slot penetrating the disk-shaped valve body from the outer end face to the inner side;wherein the securing part in a mounted state has a mounting length such that the securing part is axially elastically deformed and generates due to the axial elastic deformation a force causing a closure tension acting on the venting slot so as to close the venting slot in the mounted state. 8. The venting valve according to claim 7, wherein the venting slot extends straight. 9. The venting valve according to claim 7, wherein the venting valve is comprised of a unitary elastomer material. 10. The venting valve according to claim 7, comprising a conical member, wherein the securing part is connected by the conical member to the end member. 11. The venting valve according to claim 7, wherein the force is an axial force. 12. The venting valve according to claim 11, wherein the securing part is an insertion part. 13. The venting valve according to claim 12, wherein the securing part has an end section that is thicker than a remaining section of the securing part.
