Claim:
A closure fastener for mounting in an opening in a thin wall such as a sheet metal cabinet door, a sheet metal cabinet flap, a sheet metal cabinet housing wall or the like, where the closure fastener has an elongated, substantially cup-shaped housing whose edge passes into a flange and which has, at one end, a bearing support for an actuation lever and, at its other end, a lock device for the actuation lever in its position in which it is swiveled into the housing, and a fastening device which clamps the thin wall between itself and the flange, an improvement therein comprising that: the housing has a partially spherical bearing surface with a cylindrical bore hole proceeding from it; a partial ball with a first bearing for a closure drive shaft extending through the cylindrical bore hole; and a second bearing for the actuation lever being arranged in the partial ball; the two bearings enabling a rotation of the partial ball in relation to the housing and a swiveling of the actuation lever in relation to the partial ball around an axis vertical to the closure drive shaft and to the extension of the lever, where the first bearing is formed by a slot which extends in the partial ball in the direction of the center of the ball and forms an annulus sector, the end of the closure drive shaft extends into the end of the slot and the slot has undercuts extending substantially coaxial to the annulus sector, a transverse pin arranged near the end of the closure drive shaft for sliding along at these undercuts.
