The canopy (16) is pivotally connected to a horizontal (13) of an animal stall. The connection comprises at least one U bolt (21) whose arms are connected to the canopy so that it can be selectively displaced along the arms and locked in a selectively displaced along the arms and locked in a selected position. The U bolt (21) is loated and retained on a bar by a bracket (2) which is itself rigidly secured to the bar by a U bolt (26). The bracket covers the base of the U bolt (21) and allows it some freedom of movement. The bracket provides stops to limit pivoting movement of the canopy.
