Abstract

The invention relates to a joining arrangement for connecting a pipe to a system, especially a hydraulic clutch disengagement system. The joining arrangement comprises a joining member which can be fixed to a final section of the pipe and is to be connected to an opposite piece that is fastened to the system. The joining member positively embraces at least one radially prominent protrusion of the pipe for fastening purposes.

Claims (18)

1. A connecting member for connecting a pipe ( 1 ) to a system, comprising:

a first housing half ( 4 );

a second housing half ( 5 ) attachable to the first housing half;

a first opening at a first end, the first opening having a first diameter;

a second opening at a second end, opposite the first end, having a second diameter;

a first bore extending from the first end toward the second end and having a first uniform diameter equal to the first diameter;

a second bore extending from the second end toward the first end and having a second uniform diameter equal to the second diameter;

a groove in contact with the first and second bores and having a third diameter greater than the first or second diameters;

centering mechanism for the first and second halves;

a sealing ring abutting the first end of the connecting member and having substantially the same internal diameter as the first diameter; and,

at least one fastening element, with a catch connection, arranged to fix the first half to the second half, wherein the catch connection includes a barbed protrusion on the first housing half for lockingly engaging with an indentation in the second housing half, wherein an outer contour of the connecting member is adapted to a contour of a receiving area of a corresponding opposing piece accommodating the connecting member, and wherein the first and second halves are adapted for connection to the corresponding opposing piece in the system and are adapted to surround a first radially prominent protrusion ( 3 ) on an end section of the pipe in a form-fitting manner.

2. The connecting member as recited in claim 1 , wherein the centering mechanism comprises at least one centering pin ( 6 , 6 ′) and a corresponding receptacle ( 7 , 7 ′) on each of the housing halves.

3. The connecting member as recited in claim 1 , wherein the first and second housing halves ( 4 , 5 ) are designed to be complementary to one another.

4. The connecting member as recited in claim 1 , wherein the groove is adapted for facing the pipe ( 1 ), and said groove is adapted to accommodate the first radially prominent protrusion ( 3 ) on the pipe ( 1 ).

5. The connecting member as recited in claim 1 , wherein at least one second radially prominent protrusion ( 12 ) is provided on the end section of the pipe ( 1 ) that is to be connected.

6. The connecting member as recited in claim 5 , wherein the sealing ring is adapted to engage the second protrusion ( 12 ).

7. The connecting member as recited in claim 6 , wherein the sealing ring is an O-ring ( 13 ).

8. The connecting member as recited in claim 1 , wherein the connecting member ( 2 , 2 ′) is made of plastic.
