The butt joint is pivotally connected to the joint stand by means of a pivot member. A latch member is pivotally mounted between lips of the joint stand. The latch member is biased by a spring into engagement with the pivot member. A groove formed within a forward end of the arm receives a portion of the latch member when the handrail in a fully extended position for preventing pivotal movement of the joint stand relative to the arm.
