Abstract: The invention relates to a clamp slide rail mounting device for the reversible attachment of a mounting slide within a profile rail, where one or more objects can be attached to the mounting slide and the mounting slide can be guided within the profile rail. The mounting slide features a spring latching element with spring latching element depressions, which is placed within a groove with groove latch projections, where a rotation of the spring latching element around a spring latching element longitudinal axis causes the groove latch projections to engage form-fittingly into the spring latching element depressions.
