Claim:
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; and holding 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; and wherein 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°.
