The invention relates to a coupling between a first body (3) with a hole and an end zone of a second body (2) to be inserted therein, in which hole extends a ring (6), which ring is elastically deformable such that it bends when said end zone is inserted and scrapes over the surface thereof with its free edge such that the movement in backward direction is blocked. The coupling has the feature that the ring has an interruption with two ends which are directed toward each other and which are displaced away from each other in the direction of the axis such that the ring has a helical form, such that the free end edge of the ring has an inclining position corresponding to a helix, as a consequence of which, when the second body is rotated relative to the first body, the second body can be removed by a screwing movement from the hole of the first body.

L~invention concerne un accouplement entre un premier corps (3) avec un trou et une zone d~extrémités d~un deuxième corps (2) à introduire dedans, un anneau (6) se prolongeant dans ledit trou, ledit anneau étant élastiquement déformable de façon à plier quand ladite zone d~extrémités est introduite et racle sa surface avec son bord libre pour bloquer le mouvement vers l~arrière. L~accouplement se caractérise en cela que l~anneau a une interruption avec deux extrémités qui sont dirigées l~une vers l~autre et éloignées l~une de l~autre dans le sens de l~axe de façon que l~anneau ait une forme hélicoïdale, de façon que le bord d~extrémité libre de l~anneau ait une position inclinée correspondant à une hélice. Ainsi, quand le deuxième corps est tourné par rapport au premier corps, le deuxième corps peut être retiré par un mouvement de vissage du trou du premier corps.
