An adjustable bracket includes a first bracket portion with a first leg and a first bar element, a second bracket portion with a second leg and a second bar element, and a hub assembly supported on at least one of the first and second bracket portions. The hub assembly can be configured to couple a flexible hose to the adjustable bracket. The first bar element can be telescopically received by the second bar element so that a distance between the first and second legs is selectively adjustable. A fastener can fix the first and second bar elements in a desired relationship. The hub assembly can include first and second support members that are pivotably connected to rotate between open and closed positions. The second support member may have a slot that allows the second support member to rotate and move laterally with respect to the first support member.
