A ceiling track system including a guiding rail, in which at least one wall element is received and an encasing element that is affixed to the guiding rail. A long leg extends in a vertical joining direction and has a latching geometry, into which a latching hook can be latched such that the encasing element is affixed to the guiding rail in a self-retaining manner. The long leg has a web with a projection. The guiding rail has a groove into which the projection engages for the purpose of self-retaining the encasing element. Adjacent to the groove the guiding rail has a screw reception into which a screw element is screwable by which a clamping action is achieved. The screw reception is at an angle with regard to the vertical joining direction.
