The invention relates to a shuttle-cock shaped device consisting of a conically shaped basket (1) with an approximately cylindrical fixing peg (2) located in the region of the basket tip. This is limited at least at its outer end by a radially projecting edge (3) with a large diameter. It serves for fixing an impact cap (4) made of elastically deformable material, which has a semi-spherical frontal side (5) and an approximately cylindrical reverse section (6) of the same diameter with a central opening (7). Said latter can be moved axially to the fixing peg (2) by effecting temporary radial widening of the central opening in the region of the radially projecting edge (3). In order to secure the position of the impact cap (4) on the fixing peg (2) of the basket (1) at a moved' position, a flat pressring (8, 9) made of rigid plastic material with an inner diameter, which is slightly smaller than the outer diameter of the impact cap (4), is provided. Said ring (8, 9) can be moved by elastic pressure deformation of the reverse cylindrical segment (6) of the impact cap (4) to a radial position above the fixing peg (2) of the basket (1). |
