Embodiment Construction

[0045] figure 1 An exploded view is shown of the adapter 1 as connecting element, which is composed of a first adapter part 2 as a first connecting part, a sealing part 3 as a sealing element and a cap 4 as a locking element. The adapter part 2 is provided and designed for connection to a hose or another hollow body through which liquid or gas can flow. For this purpose, the adapter part 2 is inserted into a corresponding hose or slipped or threaded on a corresponding hose. The corresponding connection of the adapter part 2 to such a hose takes place at the first end 5 of the adapter part 2 .

[0046] During normal operation of the adapter 1 , the seal 3 is largely accommodated in the inner region of the adapter part 2 .

[0047] The adapter 2 has a thread 7 at a second end 6 opposite the first end 5 . The thread is provided and set up to enable the cover 4 to move along the thread 7 . For this purpose, the cover 4 is provided with locking lugs 8 which engage into the thre...

Abstract

The invention relates to a connecting element for connecting two hollow bodies through which a fluid can flow, comprising a first connecting part (2), which can be brought into fluid-tight flow connection with a first of the hollow bodies through which a fluid can flow, a sealing element (3), which is arranged at least partially in an inner region of the first connecting part (2), and a securing element (4), which is arranged on an outer face of the first connecting part. According to the invention, the securing element (4) can be transferred from an unsecured position to a secured position, wherein the securing element (4) acts on the sealing element (3) in the secured position in such a way that an internal diameter (d) of the sealing element (3) is smaller than when the securing element (4) is in the unsecured position, such that a fluid-tight connection between the inner region of the first connecting part (2) and an inner region of a second connecting part (13) results when the second connecting part (13) is accommodated in the inner region of the first connecting part (2). The connecting element (1) is intended and designed in particular to accommodate a female Luer lock connection in the inner region of the connecting element, such that a seal over the outside of the female Luer lock connection is realised in the secured position when the female Luer lock connection is accommodated in the inner region of the first connecting part (2). The invention further relates to a connecting assembly in which such a connecting element is used.

Description

technical field [0001] The invention relates to a connecting element according to the preamble of claim 1 and a connecting device according to the preamble of claim 13 . Background technique [0002] Numerous connection possibilities are known from the prior art for connecting two hoses or other hollow bodies through which fluid can flow. Usually a Luer lock connector is used which is partly provided with a locking nut for screwing. A connector of this type is sealed via the abutment surface between the outside of the conically shaped inner cone and the outside of the likewise conically shaped outer cone. In this case, a thread is provided around the inner cone, into which thread the outer cone can be screwed via a correspondingly shaped collar. Additionally, such Luer lock connectors can be locked by means of a union nut in order to prevent accidental opening. The inner cone is also referred to herein as a male Luer lock and the outer cone as a female Luer lock. [0003...
