ABSTRACT:
The invention pertains to a spacer for each of two adjacent slats of a vertical blind, each of which is attached at its upper end section to a slat holder which can move along a track, essentially consisting of a lengthwise, strip-like section which at one end section can be firmly connected in a positive manner by means of a first connection element with a second connection element of a first slat holder and can be guided along a guide on an adjacent second slat holder so that it can be moved relative to the second slat holder, and which has at its end section facing away from the first slat holder a catch by means of which it can be retained in the guide when the slats are drawn apart, wherein the first connection element is configured so that it can alternatively be firmly connected at at least two points lying behind one another along the length of the spacer to a trolley.
