<p>The device has a case (10) comprising a front surface (12) provided with a marking portion, where the marking portion and a label-protecting cover (110) form a reception housing opened towards the exterior through a slit. A pull rod (120) is translationally mounted in the housing. The rod has a rim (121) along a side for partially closing the slit, when the rod is completely engaged in the housing. A blocking unit is formed by a boss and a stop and blocks the rod on the case in a retracted position, in which the rod is retracted outside housing.</p> |
