Hose or pipe connector

The invention relates to a hose or pipe connection element with a spring action in a locking position held segment insert, which has a cone with which a longitudinally displaceable release sleeve cooperates in such a way that when they are moved in the direction of the cone of the segment insert is transferred against the spring action in an unlocked position.

A connecting element of this type is specified in the German Offenlegungsschrift 1 475 7 ^ 9, where the segment insert is known as two-part segment chuck is formed, which engages in the locked state by a spring ring in an annular groove. This design has the disadvantage that the segment chuck is expensive to manufacture and during the assembly and disassembly process can be lost, since the release sleeve during the installation of the release sleeve on the conical part of the segment chuck by the action of the spring ring tends to slide off the conical area.

It is the object of the invention to provide a hose or pipe connection element to provide the locking mechanism of which is simple and cheap to manufacture and during assembly or disassembly can not be lost.

Therefore a hose or pipe connection element is included one held in a locking position by spring action Suggested segment insert that has a cone, with which a longitudinally displaceable release sleeve cooperates in such a way that when it is moved in the direction of the cone Segment insert against the spring action in an unlocked position is transferred, the segment insert according to the invention as a slotted, ring-shaped tension spring with several tension shoes that taper conically in the axial direction is formed, which are supported on an annular surface of the connected hose or pipe.

In an advantageous embodiment of the invention is a locking sleeve that is firmly connected to the connecting element provided, which secures the tension spring against axial displacement, with a spring-loaded, attached to the the release sleeve supporting the locking sleeve is accommodated in a longitudinally displaceable manner by the tension spring «

A simple assembly and disassembly without tools can be achieved become, if the release sleeve with a protruding from the connecting element, to the pluggable hose or tube is preferably provided coaxially extending collar.

According to a further feature of the invention, the ring surface can be designed as a circumferential bead. He can with one The hose must be vulcanized and in the case of a pipe, e.g. through an upsetting process can be created.

However, the annular surface can also be designed as a circumferential groove be, whereby an even smaller connecting element can be created.

The inserted one is expediently sealed Hose or pipe through at least one O-ring that can be displaced in the sliding direction. This known measure will ensures that the O-ring is not damaged when the hose or pipe is inserted.

The subject matter of the invention will be based on an embodiment shown in the accompanying drawing are explained in more detail. Show in the drawing

1 shows a connecting element designed according to the invention with an inserted pipe end / partially cut and

Fig. 2 is a plan view of a segment insert.

A connecting element 1, which is designed as a T-piece in FIG. 1, is used to accommodate hoses or pipes, of which only one end of a pipe 2 is shown for the sake of simplicity. This is provided with an annular surface 3, which represents a circumferential bead 4 and is created, for example, by an upsetting process. The bead k serves to support tension shoes 6 stamped out of an annular, slotted tension spring 5, the latter two parts forming a segment insert 7 which is inserted into the connecting element 1 by means of a locking sleeve 8 - secured against axial displacement. A release sleeve 10 loaded by a spring 9 is supported on the locking sleeve 8 and has a collar 11 which protrudes from the connecting element 1, preferably running coaxially with the tube 2.

When the tube 2 is pushed into the connecting element 1,

by a front tube bevel 12 in the axial direction tapered clamping shoes 6 pressed outwards and then slide over the molded bead 4 until they are attached to it Support the side surface. The sealing of the inserted tube 2 takes over in the illustrated embodiment Q-ring 131 which can move in the sliding direction of the pipe 2, which is known to significantly reduce the risk of injury will.

To release the connection, the collar 11 of the release sleeve 10 is shifted against the pressure of the spring 9 in the direction of the clamping shoes 6. The beveled, front end of the release sleeve 10 comes to rest on the conically tapering area of the clamping shoes 6 and spreads them until the bead k of the inserted tube 2 loses its supporting function. The tube 2 can now be pulled out in a simple manner.

The invention is in no way limited to that shown and described embodiment. Rather, pipes can also be connected to one another or pipes and hose lines quickly and safely connected and detached from each other in the same way. The fasteners can also have an angle or cross shape in addition to a T-shape, but can also be designed as a straight connecting piece be.
