Greasing sleeve

A greasing device (20) for a contact wire (14) which is configured to be clamped into a conductor rail (4) for an electrical energy supply of a pantograph of a rail vehicle, comprising:

• a basic body (21) extending in a longitudinal direction (1), a transverse direction (11) perpendicular to the longitudinal direction (1) and a vertical direction (9) perpendicular to the longitudinal direction (1) and perpendicular to the transverse direction (11),
• a passage opening (25) penetrating the basic body (21) from a front side, seen in the longitudinal direction (1), to a rear side, seen in the longitudinal direction (1), through which the contact wire (14) is configured to be moved in the longitudinal direction (1), and
• a supply line (41) leading into the passage opening (25) for introducing a grease which is configured to be applied to the contact wire (14),
• wherein
• the passage opening (25) as seen in the longitudinal direction (1) following the supply line (41) has a nose (49) oriented on an upper side as seen in the vertical direction (9) which is configured to push the contact wire (14) against a bottom side (54) of the passage opening (25) as seen in the vertical direction (9).
