| 摘要 |
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.
