Abstract

For greasing the end of a reinforcement (2) surrounded by a sheath (3) and retained in a truncated cone shaped ring of jaws (6) coacting with a truncated cone shaped housing (5) formed in an anchorage plate (4), which housing is closed by a cap (11), a longitudinal rectilinear groove (12) is formed in this housing and in this cap is formed an orifice (13) automatically aligned with the groove at the end of fitting of the cap and the inner volume of the assembly is filled with grease through a rectilinear hollow needle (14) passing successively through said orifice and said groove.
