Description

Tap head The present application is a divisional application of application number 201780056360.5 (international application number PCT/DE 2017/000295), entitled "removable tap with spring element for fixing and pre-pressing", from date 2017, 09, 12. Technical Field The present invention relates to a tap for making a fluid connection between at least two connector parts and for breaking the fluid connection. Thus, the tap is preferably designed to be detachable or detachable. Background Taps for forming a fluid connection are known from the prior art. For example, publication EP0863340A2 discloses a tap with a housing and a tap rotatable within the housing, which tap in its operating position is supported with a sealing surface against the sealing surface of the housing and can be moved out of its operating position and into an intermediate position (b) when the detachable connection of the tap to the housing is released, in which intermediate position (b) the sealing surface is not in contact and the housing and the tap remain connected. The tap is thus locked to the housing in a form-fitting and positive locking manner and can be moved into an intermediate position when the locking is overcome. Particularly in the biological and medical fields, it must be ensured that a tap that can be used in a variety of ways can be easily disassembled for cleaning by rinsing and for disinfection, wherein assembly and disassembly of the tap should be possible and easy. Furthermore, such a tap should preferably be capable of being manufactured at low cost. Disclosure of Invention It is therefore an object of the present invention to create a preferably detachable tap that can be easily assembled and disassembled and is therefore inexpensive. According to the invention, the previously mentioned task is achieved by means of a tap according to the main claim of the invention. The tap according to the main claim of the invention preferably comprises at least one connection and disconnection element for making and breaking a fluid connection, a manual actuation element for rotating the connection and disconnection element, and a body. Thus, the connecting and disconnecting element is at least partially conical and comprises at least one passage opening for forming a fluid connection, wherein the manually actuated element and the connecting and disconnecting element are mechanically coupled. Preferably, the manual actuation element and the connecting and disconnecting element are elements of a single device, so as to be always connected to each other. The body comprises at least one connector part and preferably a plurality or all connector parts, and an interior space for receiving the connecting and disconnecting element, wherein the interior space comprises a contact surface for contacting the connecting and disconnecting element, wherein the contact surface has at least partially a female configuration with respect to the conical surface part of the connecting and disconnecting element. According to the invention, at least one spring element is provided for positively securing the position of the connecting and disconnecting element relative to the body and preferably for generating a surface pressure and/or for securing the contact surface with the conical surface part of the connecting and disconnecting element. The spring element is therefore preferably arranged in or on the body. Furthermore, the connecting and disconnecting element for disassembly or assembly can be moved relative to the spring element in the axial direction of extension of the connecting and disconnecting element. This solution is advantageous in that a simple and thus inexpensive arrangement is provided, wherein the spring element creates a positioning and fastening of the connecting and disconnecting element with respect to the body. As a result, good assembling and disassembling capabilities are produced as a result. Other embodiments are the subject of the subordinate claims of the invention and the objects of the following description. According to a preferred embodiment of the invention, the connecting and disconnecting element comprises an extension which is supported against a conical portion having a smallest diameter in the axial extension direction of the connecting and disconnecting element, wherein the extension comprises a wall, wherein the wall may be circumferential and preferably inclined towards the axial extension direction, wherein at least one spring element or at least one securing means acted on by the spring element is in contact with the wall for generating a pulling force in the connecting and disconnecting element, preferably for generating a surface pressure between the contact surface and the conical surface part of the connecting and disconnecting element. This embodiment is advantageous in that, in particular, due to the interaction of the inclined wall with the spring element or with the securing means, a sealing effec
