t is disclosed a hook-like tensioning device destined to retain clotheslines in stretched condition. Said tensioning device is composed of the push rod 5 of the tensioner receiving the screw 9 having hexagonal or cross head, and of the outside cover 13 of the foregoing tensioner. When the head of the screw is turned by hand or with a spanner, the push rod of the tensioner stretches out the wire ropes or the cordons in the horizontal position, without forming loose segments on them. The advantages of the invention are that one can, in minimum time, stretch out the wire ropes or the cordons of the clothes lines structure in a mutual horizontal or parallel disposition, and that in case of looseness due to the clothes weight, the invention dispenses with dismantling, since the wire ropes or cordons return, at least rotations of the tensioner's screw, to the desired position. |
