8. The flared screw fitting (1\u2032) according to claim 1, wherein the internal mantle surface (18) of the transmission body is provided, in an area in which it is in contact with the external mantle surface (19) of the tulip flare (11) in the hand-tight pre-mounted state, with a bead (29) which projects inward in relation to the remaining mantle surface (18).
9. The flared screw fitting (1\u2033) according to claim 1, wherein the internal mantle surface (18) of the union element is provided with teeth (32) in an area in which it is out of contact with the external mantle surface (19) of the tulip flare (11) in the hand-tight pre-mounted state.
10. The flared screw fitting (1\u2033) according to claim 8, wherein, in the final mounted state, the bead (29\u2033) and the teeth (32) are each at least partially dug into the external mantle surface (19) of the tulip flare (11).
11. The flared screw fitting (1, 1\u2032, 1\u2033, 1\u2032\u2033) according to claim 1, wherein a tulip flare (11) is at least predominantly located in an axial section of the flared screw fitting (1), in which the threaded sections of the connecting piece (2, 2\u2032) and the union element are engaged with one another.
12. The flared screw fitting (1, 1\u2032, 1\u2033, 1\u2032\u2033) according to claim 1, wherein the union element is provided in the area of the tulip flare (11) with a continuous conical internal mantle surface (18).
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An assembly comprising:
a field hockey stick having a shaft with a free end;
a removable cover for said shaft of said hockey stick comprising a cap configured and dimensioned for mounting on said free end of said shaft, wherein said cap is cup-shaped and comprises a planar bottom wall with an outer peripheral edge and a generally tubular upstanding side wall having a first end and a second end, said first end being attached to said outer peripheral edge of said bottom wall; and
a flexible, resilient membrane-like tubular sheath having a thickness of 116\u2033 to \xbc\u2033 which is configured and dimensioned to be rolled over itself to form a rolled configuration and having two opposite ends, one of which is coupled to said second end of said side wall of said cap and the other of which defines a free end, and wherein said tubular sheath is dimensioned and configured so that it can be unrolled longitudinally onto and along said shaft of said hockey stick with said cap abutting and mounted on said free end of said shaft and said sheath being dimensioned and configured to afford a tight friction fit over said shaft when unrolled and which can be rolled longitudinally in the opposite direction along said shaft of said hockey stick towards said free end of said hockey stick and said cap, to permit removal of said cover from said hockey stick and wherein said cap has a thickness which is greater than the thickness of said sheath.
