Abstract: A hose remover includes an arcuate flexible section with flexibilities on both opposite sides of the arcuate flexible section and capable of tying close to or being away from each other and restoring their original positions; a first extending portion, formed and extending from a side of the arcuate flexible section; a second extending portion, formed and extending from the other side of the arcuate flexible section which is different from the side of the first extending portion; two hose clamping portions, formed at ends of the first and second extending portions respectively, such that the arcuate flexible section, the first extending portion, the second extending portion and the hose clamping portion are in an integral structure mode.

Abstract: A seat back hanger adapter includes a securing unit having a main part with two end caps resiliently mounted to two ends of the main part. The main part is a hollow part and has an opening defined in one side thereof. A connection unit is inserted into the opening and has two hooking members received therein. A resilient member is biased between the two hooking members. Each of the hooking members has a button and a hooking portion, wherein the button protrudes from outside of the connection insertion, and the hooking portions are engaged with two notches in the main part. An organizer is pivotably connected to the connection unit. The connection unit is easily separated from the main part by pushing the buttons of the two connection members.
