A traffic control drum is disclosed as an upright member having upper and lower ends, a support base adapted to rest on a support surface and an operator releasable mechanism for attaching the lower end of the member to the support base, so that the member is oriented in an upright relation to the support surface. The support base has an element exposed to be stepped on by the operator to hold the support base still on the support surface. The member has a mechanism disposed to be manually grasped by the operator, whereby the operator may urge the member away from the support base, while the operator holds the support base still with respect to the support surface to thereby effect release of the upright member from the support base.

A traffic control drum comprising: an elongated hollow member having upper and lower ends, said upper end being enclosed by a top-portion and said lower end being open; the interior of said lower end including a plurality of contiguous interior flat faces arranged parallel to the longitudinal axis of said member and next to each other about the periphery of said lower end in a first closed configuration to define an inside wall; a support base adapted to rest on a support surface, said support base including a plurality of exterior flat faces arranged parallel to the center axis of said base and next to each other about the periphery of said support base in a second given configuration to define an outside wall; said first and second given configurations matching each other so that each of said exterior faces mate with a corresponding interior face when said interior of said lower end covers and is supported by said outside wall of said support base; a plurality of slots, each of said slots defined in a different one of said plurality of exterior flat faces, said slots extending from said face inwardly toward the center axis of the support base; a plurality of detents, each of said detents defined in a different one of said plurality of interior flat faces, said slots extending inwardly toward the longitudinal axis of said hollow member. each of said detents adapted to be disposed in a different one of said slots to thereby releasably attach said hollow member to said support base; and a plurality of planar rigid foot pads, each of said foot pads extending outwardly from said support base so as to be free of said releasable attaching arrangement.
