Abstract: A beverage container receptacle adapted for installation relative to fixed first and second structures. The receptacle includes a container-holding first part having a container rest and a periphery that defines a void in which is received a portion of the fixed first structure that extends along a first axis. The periphery at least partially surrounds the first axis, and the receptacle is supported by the first structure when it is installed relative thereto. The receptacle also includes a receptacle-retaining second part slidably positioned relative to the first part. The second part is adapted for movement relative to the first structure received in the void and toward engagement with the second structure. The receptacle is adapted for being supported against angular movement in at least one direction about the first axis through the engagement of the second part with the second structure.
