Abstract: The invention relates to a coupling between two objects via a coupling element. Each object comprises a panel with a continuous hole with four inward protruding tongues which are disposed at 90° to each other and extend over angles of about 22.5°. The coupling element comprises a shank, an insert stop member on both sides so that the coupling element can be inserted in the one or the other direction into the hole, four locking cams on each end zone of the shank which each extend over angles of 22.5° disposed at 0°, (90°?22.5°), 180°, (270°?22.5°), and rotation stop members. The coupling element can be inserted into the hole in a chosen orientation as desired in one of four equidistant angular positions and then rotated through about 22.5° in the one or the other direction, wherein rotation locking means fix the chosen angular position.

Abstract: A coupling between a first body with a hole and a cylindrical end zone of a second body to be inserted therein, in which hole extend elastically deformable tongues, the free end edges of which tongues lie on a circle, the diameter of which is smaller than the outer diameter of the end zone, which tongues bend in the insertion direction when the end zone is inserted and scrape over the surface thereof with their free edges such that after inserting the end zone over some distance the movement in a backward direction is blocked. The end edges of the tongues have an inclining position corresponding to a part of a helix, so that during a relative rotation of the two bodies, the form of the helix is followed whereby an axial relative movement also occurs and the end zone can be removed from the hole.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a coupling between a first body (5) with a hole, and a cylindrical end zone of a second body (1) by means of tongues (8) which, when said end zone is arranged, scrape over the surface thereof, whereby the backward movement is blocked. The coupling has the feature that the tongues form part of an interrupted ring (3); the tongues are the windings of a helix; the tongues are inclined in the direction of arrangement; the end zone can displace along the helix during arrangement with elastic deformation of the ring; additional pressure forces occur between the tongues and the end zone when a force in opposite direction to the insertion direction is exerted between the ring and the second body; whereby, when the second body rotates relative to the first body, the helix is followed so that an axial movement also occurs and the end zone of the first body can be removed.
