<p>For mechanism for releasably locking or braking an elongate element and associated structure comprises mechanism including a member adapted to be mounted on the associated structure and providing clutching surface means engageable with one side of the elongate element. A locking lever has one end pivotally mounted on the member and has intermediate its ends a gripping clamping clutch area thrustable into locking, gripping, clamping engagement toward the clutching surface means for thereby locking the element and the associated structure against relative movement. For rocking the lever in its locking mode a force multiplication device comprises a roller driven as by means of an actuator plunger into force multiplying engagement between a fixed shoulder and a roller on a free end portion of the lever.</p> |
