The invention is based on a releasable connection between two housing parts, the outer circumference a cylindrical extension of one housing part, an annular groove and the wall of a cylindrical, the shoulder receiving recess of the other housing part in a radial Direction of the said annular groove adjoining the annular groove and into the annular grooves oval ring body is located.

. In contrast, the object of the invention is to provide compounds of the type mentioned improve that not only in the direction of mating and disassembling the housing parts a positive, but also a non-positive, adjustable connection in the direction of rotation is achieved, which is cheap to manufacture and allows easy assembly and disassembly.

To solve this problem, the invention provides that the ring body is in the expanded position a circular shape with a diameter lying between the bottom diameter of the two annular grooves has, in the installed position by two adjustable, radially offset from one another by 180 ° acting pressure parts is pressed to the oval, the wall of the recess at the outer end has an enlarged diameter that encompasses the approach with a wide clearance. ; In solving this problem, the following design features, known per se, are used: It is at a rotatable handle connected to a bolt has become known, the coupling between the To effect bolt and the handle by a coupling member inserted between the two, this The coupling member is an annular spring part.

It has become known for the connection between a hub-like part and a bolt-like part, to bring about a rotation lock in that in the hub-like part a stud screw ·; is screwed in with a cylindrical extension, where V; the cylindrical extension engages in a recess in the shaft part.

The invention achieves that in compounds of the type mentioned in the first paragraph in Direction of rotation creates a non-positive, adjustable connection that is cheap to produce and one allows easy assembly and disassembly. This is achieved in the invention in that the Connecting ring is formed circular with a simple manufacturing possibility and in a corresponding Training at the end of the recess can be pushed in in a simple manner and through the Pressure medium, in particular the pressure screws, so detachable connection of two housing parts

is pressed oval that it is in the oval pressed state not only the axial lock, but also the Anti-twist protection takes over.

The invention is explained in more detail using an exemplary embodiment in the drawing. Here shows

F i g. 1 shows a cross section through the connection and

Fig. 2 is a longitudinal section through the connection.

The detachable connection between two housing parts 1, 2 can be seen in the drawing. The outer circumference a cylindrical extension 3 of the housing part 1 has an annular groove 4 and the wall of a cylindrical, the extension 3 receiving recess 5 of the other housing part 2 in a radial Direction of the said annular groove 4 adjoining annular groove 6. Located in the annular grooves 4, 6 an oval ring body 7.

The annular body 7 comprises in Equipped position, a circular shape with a between the bottom diameter of the both annular grooves 4, 6 lying in diameter and is pressed in the mounted position by two ^v mutually offset by 180 °, adjustable, radially acting pressing members 8 to the oval. The wall of the recess 5 has at the outer end an enlarged diameter 9 that encompasses the extension 3 with a wide clearance.

The adjustment means are as screws 8 of the recess protruding into the annular groove 6 of the recess 5 5 having housing part 2 formed.

Claims (2)

Patent claims: 1. Detachable connection of two housing parts, the outer circumference of a cylindrical An-N Set of one housing part an annular groove and the wall of a cylindrical, the approach receiving Recess of the other housing 709 649/191 part one in the radial direction to the said Has annular groove subsequent annular groove. and an oval ring body in the ring grooves is located, characterized in that the annular body (7) in the expanded position a Circular shape with one lying between the bottom diameters of the two annular grooves (4, 6) Diameter, in the installed position by two adjustable, offset by 180 ° to each other, radially acting pressure parts (8) is pressed towards the oval, the wall of the recess (5) at the outer end a widened, the approach (3) with a wide clearance Has diameter (9). 2. Connection according to claim 1 using screws, characterized in that that the pressure parts (8) as in the annular groove (6) of the recess (5) protruding screws of the Housing part (2) having recess (5) are formed.
