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.
