They successively pass through an opening 21 of the sliding plate 20 and the slides 11 of the fixing plate 10.
  • the connecting means can occupy two configurations: an unlocked configuration, in which they allow the relative displacement of the sliding plate 20 in the longitudinal direction relative to the fixing plate 10, and a locked configuration, in which the sliding plate 20 is secured to the fixing plate 10.
  • This arrangement allows a first degree of freedom in the longitudinal direction, in a direction and an amplitude defined by the direction and the length of the longitudinal slideways 11.
  • This displacement is of longitudinal translation type in this direction.

It further comprises two adjustable screws, not shown, arranged respectively in threaded openings 42 on each side of the opening 41, intended to cooperate with the upper surface of the apertures 21 in abutment.
  • openings 45 at its corners, intended to receive fastening means, for example screws, for its attachment to a second part of the rifle butt.
  • the relative positioning of the male part relative to the female part 40 of the connecting device makes it possible to define two other degrees of adjustment.
  • the male part may be more or less sunk into the female part, that is to say that the adjustment plate 30 may be more or less sunk into the longitudinal opening 41, according to a displacement of vertical translation type .
  • This amplitude which depends significantly on the height of the adjustment plate, can be at least 3 cm, even at least 5 cm, and / or preferably between 3 and 7 cm.
  • the longitudinal opening 41 of the female part has a dimension slightly greater than the horizontal section of the plate, in particular at its length.
  • This configuration allows a clearance which allows a respective rotation of the adjustment plate 30 relative to the female portion 40 along a transverse axis y, that is to say that the front and rear portions of the adjustment plate can be depressed according to a different depth through the longitudinal opening 41.
  • the amplitude of the rotation is chosen, preferably at least 3 degrees, or even 5 degrees, and / or preferably between 5 and 15 degrees.
  • the figure 11 represents the female portion 40 of the connecting device attached to a second portion 55 of a wooden rifle butt.
  • a slight notch 56 is made on the surface of this second portion 55, to form a horizontal receiving surface of the female part 40, thus fixed retracted in this hollow part by four screws 57.
