1. A snap fastening suitable for mounting fittings in openings in a thin wall, comprising: a head part which is to be arranged on one, outer side of the thin wall and which overlaps an outer rim of the opening;a body part which proceeds from the head part and projects through the opening in the mounted position; andholding elements which project from the body part and are resilient in direction of the body part's outer surface against spring force, a free end of these holding elements being provided with a first inclined surface configured to support the body part without play on the rim or edge of the opening of the other, inner side of the thin wall, the free end further comprising a second inclined surface configured for slam action;wherein said body part, holding element, and a spring generating the spring force are separate parts;wherein said holding elements are slides which are arranged so as to be displaceable in a channel that is parallel to a plane of the thin wall and is rectangular in cross section, the channel having an inside rectangular cross-section orthogonal to the direction of the sliding movement of the slides;wherein said holding elements are guided inside the channel having four inner walls as guiding surfaces, namely a head wall, two side walls, and a bottom wall, wherein the guiding surfaces of the four walls are flat and abut perpendicular to one another;wherein said holding elements comprise two diametrically opposed holding elements having identical measures and being symmetrical with one another;wherein said slides are held against pressure spring force by a hook arrangement locking between the slides or in the channel; andwherein the first inclined surface is inclined with respect to the plane of the thin wall at an acute angle of more than 0° and less than 90°. 2. The snap fastening according to claim 1; wherein, when the two diametrically oppositely arranged holding elements are loaded to different extents, the holding element upon which the smaller load is exerted is made of flexible plastic and the other holding element, upon which the greater load is exerted, is made of rigid material. 3. A snap fastening suitable for mounting fittings in openings in a thin wall, comprising: a head part which is to be arranged on one, outer side of the thin wall and which overlaps an outer rim of the opening;a body part which proceeds from the head part and projects through the opening in the mounted position; andholding elements which project from the body part and are flexible in direction of the body part's outer surface against spring force, a free end of these holding elements being provided with a first inclined surface configured to support the body part without play on the rim or edge of the opening of the other, inner side of the thin wall, the free end further comprising a second inclined surface configured for slam action;wherein said body part, holding element and a spring generating the spring force are separate parts;wherein said holding elements are slides comprising a rigid material which are arranged so as to be displaceable in a channel which is parallel to a plane of the thin wall and is rectangular in cross section and being held against pressure spring force by a pin arrangement that is arranged between the slides; the channel having an inside rectangular cross-section orthogonal to the direction of the sliding movement of the slides;wherein said holding elements are guided inside the channel having four inner walls as guiding surfaces, namely a head wall, two side walls, and a bottom wall, wherein the guiding surfaces of the four walls are flat and abut perpendicular to one another;wherein said holding elements comprise two diametrically opposed holding elements having identical measures and being symmetrical with one another; andwherein the first inclined surface is inclined with respect to the plane of the thin wall at an acute angle of more than 0° and less than 90°. 4. The snap fastening according to claim 3; wherein the pin arrangement comprises screws that can be screwed into the head part. 5. The snap fastening according to claim 4; wherein the screws determine the extent of the movement of the holding elements. 6. The snap fastening according to claim 1; wherein the cylinder has a partial dividing wall or undercut or opening edge at which slides are supported axially by a shoulder or hook. 7. The snap fastening according to claim 3; wherein the cylinder has a partial dividing wall or undercut or opening edge at which slides are supported axially by a shoulder or hook. 8. The snap fastening according to claim 1; wherein the fitting is a swivel lever latch or a folding lever latch for fastening in an elongated opening or in two shorter rectangular openings, wherein one opening receives a lever bearing and the other opening receives a lever stop, wherein at least one of the openings also serves to receive at least one body part with holding element according to claim 1. 9. The snap fastening according to claim 8; wherein the swivel lever latch or folding lever latch has a keyhole plate that is suitable for receiving the actuating lever in a lockable manner, wherein the dish forms the head part of one or two body parts with holding elements in the area of the lever bearing. 10. The snap fastening according to claim 8; wherein the swivel lever latch or folding lever latch has a dish for receiving the actuating lever in a lockable manner, wherein the dish forms the surface behind which the cam of a lever stop engages on the one hand and forms the head part of a body part with holding elements in the area of the lever stop on the other hand. 11. The snap fastening according to claim 8; wherein the holding elements are formed by slides which are held so as to be displaceable and whose movement axis lies perpendicular to the longitudinal extension of the dish. 12. The snap fastening according to claim 1; wherein the fitting is a hinge plate. 13.
