Locking members are provided and are each movably contained in radial openings in the wall of the locking head and adapted to be pushed by a control sleeve embracing the locking head into recesses in the tang of the tool. The locking members have circular-shaped segments thereon located to face radially inwardly with part of the circular edges being slidable in slots on faces having a complementary shape and being adapted to engage the tang at the end of the tool shank. |
