FIELD: mechanical engineering, in particular, attachment devices adapted for positioning on individual or group support. SUBSTANCE: apparatus has hollow cylinder of, preferably, prismatic or trapezium shape with front input part involving set of thin flexible ribs extending along side surfaces of hollow cylinder to define intermediate gap for clamping of article therein. Rod is preferably positioned in center of gap. Rod is extending coaxially of opening axis and may be inserted into inner zone of article cavity. In case end of article to be inserted is not made hollow, rod may be absent from said opening. According to alternative version of apparatus, said opening and inner ribs form gap mating shape of article end adapted for insertion. EFFECT: increased efficiency by quick mounting and dismantling of elongate articles of different diameters and provision for automatic centering of articles to be inserted. 3 cl, 3 dwg
