Rack

The invention relates to a rack comprising at least one longitudinal profile, which can be vertically aligned, to which retaining means can be attached, into which trays, cabinet elements or other shelf elements can be inserted, which retaining means are held in clamping fashion via clamping jaws on the longitudinal profile. The clamping jaws are attached to a first plate-shaped based body and to a second plate-shaped base body, which are arranged lying one atop the other and can be moved against each other, guided by guiding means, and as a result the clamping jaws can be tensioned against lateral surfaces of the longitudinal profile. A rotation axle of an eccentric for moving the clamping jaws is rotatably mounted in the first plate-shaped base body and the eccentric body protrudes into a recess of the second plate-shaped base body. A simply designed retaining means is thus obtained which can be easily clamped on the longitudinal profile.
