At least two carriages serve as pull carriages and each has a locking receptacle, whereas the pull cord is provided with at least one locking part fixed thereon. Each locking receptacle for the locking part forms a locking fit transport-fixed in both pulling directions of the pull cord, but detachable by a pulling force instantaneously exerted on the pull cord.
