Nipple chamber for cable and nipple has side walls with diminishing distance apart , with floor and opening

摘要

The nipple chamber (2) has side walls (3,4) parallel with the longitudinal direction in which the nipple extends. The space between the side walls decreases over at least part of the area between the insertion opening and the floor (20) of the nipple-chamber. At a preset distance from the floor or insertion opening, the nipple chamber is smaller than the minimum diameter of the nipple.
