Abstract
Abstract A housing ( 40 ) has a first passage ( 42 ) through which a longitudinal member ( 12 ) extends and a second passage ( 44 ) extending transverse to the first passage. A fastener ( 16 ) extends through an opening ( 50 ) in the housing ( 40 ) into the second passage ( 44 ). An axis ( 18 ) of the fastener ( 16 ) is positionable in any one of a plurality of angular positions relative to an axis ( 46 ) of the second passage ( 44 ). A spacer ( 60 ) received in the second passage ( 44 ) engages the fastener ( 16 ) and the longitudinal member ( 12 ). A pin member ( 70 ) fixedly connected to the housing ( 40 ) extends into engagement with the spacer ( 60 ) to retain the spacer and the fastener ( 16 ) in the housing and maintain the spacer in frictional engagement with the fastener to prevent relative movement between the fastener ( 16 ) and the housing when the longitudinal member ( 12 ) is disengaged from the spacer. The fastener ( 16 ) and the housing ( 40 ) are manually movable relative to each other in opposition to the frictional engagement. A clamping mechanism ( 90 ) clamps the longitudinal member ( 12 ), the spacer ( 60 ), and the housing ( 40 ) to the fastener ( 16 ) to prevent movement of the fastener relative to the housing.
