A vertical rod (16) has a spring-loaded (24) sleeve (23) holding the end of a pull cord (22). The pull cord is connected (21) to separate pull cords (19,20) moving spring-loaded (15) pivoted (14) self- tightening clamping elements (5) at the ends of the jaws (2,3). The curved jaws are pivoted together (4) at the top. A spread adjustment rod (7) has a fastening bolt (6) at one end and has a pin (10) at the other end engaging an adjustable fastening (9).
