Abstract
A connection device for a fluid duct includes a metallic holding body, a sleeve-like insert body, and a synthetic resin retaining ring. The metallic holding body is formed with a socket having an inner periphery formed with an annular groove. The sleeve-like insert body has an outer periphery and is configured to be plugged into the socket. The synthetic resin retaining ring is fixed in the annular groove so that the retaining ring will bear axially against the holding body. At least one projection is provided on the outer periphery of the insert body for biting into the retaining ring upon insertion of the insert body into the socket.
Claims25
A connection device for a fluid duct comprising:
- a metallic holding body formed with a socket, said socket having an inner periphery formed with an annular groove;
- a sleeve-like insert body having an outer periphery and being configured to be plugged into said socket;
- a synthetic resin retaining ring being formed with a slot and substantially fixed in said annular groove so that said retaining ring will bear axially in both directions against said holding body;
- and
- an anchoring means for anchoring said insert body in said socket, said anchoring means including at least one projection provided on said outer periphery of said insert body biting into said retaining ring upon insertion of said insert body into said socket.

A connection device for a fluid duct comprising:
- a metallic holding body having an outer section and being formed with a socket, said socket having an inner periphery formed with an annular groove, said inner periphery at said outer section having a first diameter and said inner periphery at said annular groove having a second diameter which is larger than said first diameter;
- a sleeve-like insert body having an outer periphery and being configured to be plugged into said socket;
- a synthetic resin retaining ring defined by a radius and formed with a slot having a width, said retaining ring being substantially fixed in said annular groove so that said retaining ring will bear axially in both directions against said holding body;
- an anchoring means for anchoring said insert body in said socket, said anchoring means including at least one projection provided on said outer periphery of said insert body for biting into said retaining ring upon insertion of said insert body into said socket;
- and
- wherein said width of said slot is selected so that said retaining ring is capable of being compressed to reduce said radius temporarily for insertion through said outer section for mounting within said annular groove.
