A pick-up in the form of a hook (4) is held in position in a readiness location projecting outwards from the shaft part (1) by a stop mechanism (16) releasable by the effect of a pressure from the loop. In thislocation, the hook is connected to the shaft part only via a first connecting point. In the area of the hook free end is a coupling component (7) which acts as second connecting point, and which works in conjunction with a holder (11) on the shaft part. The free end of the hook, by drawing in the shaft part, is insertable through the loop so as to bring it to press against the stop mechanism. This releases the pick-up hook so that it can pivot relative to the shaft part to a position in which, on one side, the coupling component grips firmly into the holder, and on the other side the connection between the hook and the shaft part at the first connecting point ceases. Thus the pick-up hook can pass through the loop despite the fact that due to the through-drawing process it remains fixed to the shaft part. |
