DEVICE FOR CONNECTING A FLEXIBLE TUBE OR PIPE, PREFERABLY A CAPILLARY

The present invention relates to a device for connecting a tube or hose, preferably a capillary, comprising a core element having a threaded section for connecting to a connection socket, and a cap element which extends around the core element in the peripheral direction offset from the threaded section in a longitudinal direction, wherein the core element and the cap element are rotationally coupled to one other in a way that a torque applied to the cap element is transferred to the core element, and above a threshold of the torque in a screw-in rotational direction of the core element a relative movement of the cap element is performed relative to the core element instead of the transfer of torque, wherein an intermediate element for providing a coupling between the core element and the cap element is arranged.
