The invention relates to a coupling between a first body (1) with a hole and a cylindrical end zone of a second body (6) to be arranged therein or thereover in an axial direction, in which hole extend a number of tongues (9), which bend elastically when said end zone is inserted and scrape over the surface thereof with their free edges such that the movement in backward direction is blocked. The coupling has the feature that each tongue forms part of a generally U-shaped clip (5) fixable clampingly over the mouth rim of the first body, and that the end edges of the tongues have an inclining position corresponding to a helix, as a consequence of which, when the second body is rotated relative to the first body, the helix is followed so that an axial relative movement also occurs and the end zone of the second body can be removed from the first body.

L~invention concerne un accouplement entre un premier corps (1) avec un trou et une zone d~extrémités cylindrique d~un deuxième corps (6) à agencer dans celui-ci ou au-dessus de celui-ci dans un sens axial, un certain nombre de languettes (9) se prolongeant dans ledit trou, lesquelles se courbent élastiquement quand ladite zone d~extrémités est insérée et racle sur sa surface avec leurs bords libres de façon que le mouvement vers l~arrière soit bloqué. L~accouplement se caractérise en cela que chaque languette fait partie d~une pince en forme générale de « U » (5) pouvant être fixée, de manière à serrer, au-dessus du rebord de l~ouverture du premier corps, et en cela que les bords d~extrémité des languettes ont une position inclinée correspondant à une hélice, ce qui permet, quand le deuxième corps est tourné par rapport au premier corps, à l~hélice d~être suivie pour qu~un mouvement axial relatif ait aussi lieu et que la zone d~extrémités du deuxième corps puisse être retirée du premier corps.
