摘要

The movable block (110) has clamps (150, 160) that are movably mounted between a locking position in which the movable block is connected to a fixed block (120) in disengageable manner and a release position in which the movable block is released from the fixed block. Each clamp is accessed via accessibility openings (159, 169) provided on a lower longitudinal surface (114B) of the movable block, where the lower longitudinal surface is different from an upper longitudinal surface (114A) of the movable block.
