At this time, in the compressor, pulling force can be imparted at two points, the first pulling point (132a) and the second pulling point (133a).

The joining mechanism (14) has a first arm (132) on which a first pulling point (132a) is set, and a second arm (133) on which a second pulling point (133a) is set.

Two pull points may further be arranged so that the application of oppositely directed forces to the first and second pull-points will lead to unfolding of the bag.

The hook includes a plurality of traction member connection portions to variously set a point and direction of application of a traction force.

The joining mechanism (14) has a first arm (132) on which a first pulling point (132a) is set, and a second arm (133) on which a second pulling point (133a) is set.

A pull-wire (18) connects a point (B) of the tube tip with a pull ring (17) at the proximal end (3) of the tube.

In some configurations, the outer layer stretches at least thirty percent prior to tensile failure.

These tensioning means act on the first section (41) of the traction member (4) via a first point of engagement (A) and on the second section (42) of the traction member (4) via a second point of engagement (B).

The construction makes it possible to provide a drawbar which completely without welded joints between legs and front part attains satisfactory tensile strength.

The tongue traction device comprises a pull plate (l), pull lines (2), and a tractor (3).

Two pull points may further be arranged so that the application of oppositely directed forces to the first and second pull-points will lead to unfolding of the bag.
