A strap assembly constructed of shape retentive but deformable and resilient dielectric material. The strap assembly includes longitudinally spaced transversely extending corrugations and is adapted to encircle an upright trash can constructed of conductive material with a first side of the strap assembly opposing the outer surface of the trash can. The corrugations define ridges spaced along the first side for abutting engagement with the can and the assembly includes longitudinally spaced openings formed therethrough. Anchor structure is provided for releasably securing the strap assembly about the can and a conductor member is threaded through selected corrugations of the strap assembly and spans the openings. A battery and electrically actuatable signal generator are serially connected in circuit structure including the conductor member and a contact member electrically connects the circuit with the can, the conductor member being laterally displaceable into electrical contact with the can to close the circuit and thus cause the battery to electrically actuate the signal structure.
