Abstract:
1. A detachable insert connection arrangement adapted to be connected to a retaining channel having a slot between two retaining edges, the connection arrangement comprising: a holder having a push-in part that includes a locking element; the push-in part being capable of being pushed into the retaining channel; a rotation pin coupled to the locking element; the locking element being at least partially rotatable in two directions; a spiral torsion spring that surrounds the rotation pin and that biases the locking element towards a locking position such that when the locking element is arranged in the retaining channel, the locking element bridges the slot and engages an inside of the two retaining edges; and the locking element being movable, upon movement of the rotation pin against a biasing force of the spring, to a non-locking position, whereby the push-in part can be removed from the retaining channel, wherein the locking element has two wings which resemble a propeller and each wing has a slide taper, and wherein, when the push-in part is pushed into the retaining channel, each slide taper is adapted to be pressed against the two retaining edges of the slot in such a way that the locking element can be turned against the biasing force of the spiral torsion spring into a position where the push-in part can be pushed through the slot.
