Abstract

A yarn-clamping device (20) includes a clamping rail (22), a clamping rod (24), configured to be inserted into a clamping volume, the clamping rod (24) having a clamping rotation movement relative to the clamping rail (22), in a clamping direction (R2), from an insertion position to a clamping position. The yarn-clamping device also includes at least one maintaining device (26) comprising an obstacle (90) configured to have a movement relative to the clamping rod, from a retracted position to a blocking position during the clamping rotation movement of the clamping rod. The retracted position of the obstacle corresponds at least to the insertion position of the clamping rod, whereas the blocking position of the obstacle corresponds at least to an intermediate position relative to the clamping rail (22), reached by the clamping rod in its clamping rotation movement, shifted with regard to the insertion position. The obstacle prevents a rotation movement of the clamping rod within the clamping volume in a direction (R3) opposite to the clamping direction.
