Abstract
The present invention relates to a mandrel comprising a radially movable portion (6, 8) and a retaining device for a sleeve (7) having an annular cross-section. Said device comprises a mounting (14), inserted in or built into the mandrel, and a retaining tab (1) pivotably mounted around an axis (3) that is in a direction parallel to the axis of the mandrel and onto said mounting (14). Said retaining tab (1) is designed to be, during use, pivotable from a first position, in which said retaining tab covers a portion of the annular surface of the sleeve (7), toward a second position, in which said retaining tab releases the annular surface of the sleeve (7). The pivotal movement from the first position toward the second position, or vice versa, is, during use, automatically actuated by radially moving the movable portion (6, 8) of the mandrel.
