摘要

The protective grid arrangement has detent elements (12) arranged at an outer edge of a protective grid (6) in its grid plane. The protective grid is formed within an area of each detent element in such a manner that each detent element is moved for locking and releasing of a detent connection (8) under area-wise flexible deformation of the protective grid radially relative to associated detent extension (10).
