Abstract

Coupling device and method of forming coupling device. The coupling device includes a first part with a first connection region, and a second part with a second connection region. A sealing ring arranged between the first part and the second part radially extends into the first connection region.

First claim

What is claimed:

1. A coupling device comprising:
a first part;
a second part;
a sealing ring; and
a clip,
wherein:
the clip is constructed and arranged to fix in a locking manner a coupling counterpart when the coupling counterpart is inserted into an open end of the first part;
the sealing ring is in contact with the first part and with the second part and extends radially along an internal surface of the first part,
the first part comprises two sloping faces having an acute angle in a direction of the clip movement,
the clip is movable in a perpendicular direction with respect to a direction in which the coupling counterpart can be inserted into the first part, and comprises a U-shaped form having two ends which are guided on the sloping faces of the first part;
at least one sloping face of the first part comprises a stop structured and arranged to block further movement of the clip toward an unlocking position from a locking position;
the two ends of the clip are arranged on one side of an imaginary plane passing through a center axis of the first part in each of the locked and unlocked positions, and
wherein the first part is connected to the second part by a material bond.

2. The coupling device in accordance with claim 1 , wherein the sealing ring is arranged in a groove at least in part formed in the first part, while a side wall of the groove is formed by an end face of the second part.

3. The coupling device in accordance with claim 1 , wherein the material bond comprises a welded bond.

4. The coupling device in accordance with claim 1 , wherein the first part extends perpendicularly in relation to the second part.

5. The coupling device in accordance with claim 1 , wherein the second part is connectable to a hose.

6. The coupling device in accordance with claim 1 , wherein the stop of the at least one sloping face is arranged on one side the imaginary plane passing through the center axis of the first part while a grippable part of the clip is arranged on an opposite side of the imaginary plane in each of the locked and unlocked positions.

7. The coupling device in accordance with claim 1 , wherein the two ends are caused to move away from each other continuously by the sloping faces when moved from the locked to the unlocked positions.

8. A coupling device comprising:
a first part;
a second part;
a sealing ring; and
a clip,

wherein:
the clip is constructed and arranged to fix in a locking manner a coupling counterpart when the coupling counterpart is inserted into an open end of the first part;
the sealing ring is in contact with the first part and with the second part and extends radially along an internal surface of the first part,
the first part comprises two sloping faces having an acute angle in a direction of the clip movement,
the clip is movable in a perpendicular direction with respect to a direction in which the coupling counterpart can be inserted into the first part, and comprises a U-shaped form having two ends which are guided on the sloping faces of the first part;
at least one sloping face of the first part comprises a stop structured and arranged to block further movement of the clip toward an unlocking position from a locking position;
the two ends of the clip are arranged on one side of an imaginary plane passing through a center axis of the first part in each of the locked and unlocked positions, and
wherein the second part comprises a stop to limit an insertion distance for the coupling counterpart.

9. A coupling device comprising:
a first part;
a second part;
a sealing ring; and
a clip,

wherein:
the clip is constructed and arranged to fix in a locking manner a coupling counterpart when the coupling counterpart is inserted into an open end of the first part;
the sealing ring is in contact with the first part and with the second part and extends radially along an internal surface of the first part,
the first part comprises two sloping faces having an acute angle in a direction of the clip movement,
the clip is movable in a perpendicular direction with respect to a direction in which the coupling counterpart can be inserted into the first part, and comprises a U-shaped form having two ends which are guided on the sloping faces of the first part;
at least one sloping face of the first part comprises a stop structured and arranged to block further movement of the clip toward an unlocking position from a locking position;
the two ends of the clip are arranged on one side of an imaginary plane passing through a center axis of the first part in each of the locked and unlocked positions, and
wherein the stop of the at least one sloping face is arranged on one side the imaginary plane passing through the center axis of the first part while a grippable part of the clip is arranged on an opposite side of the imaginary plane in each of the locked and unlocked positions.
