Embodiment Construction

[0058] First, FIGS. 1 to 3 will be described below. They show the joint 10 of the connection and the pipe 12 to which the joint 10 is mounted. The tube has a substantially radial gripping surface 14 remote from its free end 12A.

[0059] The fitting 10 includes a body 16 within which the pipe 12 may be mounted. In the installation position shown in Figures 2 and 3, the connection between the pipe and the fitting is airtight. To this end, an O-ring sealing gasket 18 can be interposed between the body wall of the fitting 16 and the wall of the pipe 12 . For example, a recess 20 may be provided in the inner wall of the fitting body for accommodating said gasket 18 so that it engages an axial portion of the wall of the pipe 12 when said pipe is fitted into the fitting.

[0060] The fitting further comprises a locking clip 22 which, as can be seen more clearly in FIG. 2 , is positioned above the wall of the fitting body 16 when held axially relative to said body. The clamp has ...

Abstract

A quick-connect fitting, the fitting (10) comprising: a body (16) adapted to be mounted in a sealing manner on a pipe (12), and a locking clip (22) elastically deformable between a locked configuration and an unlocked configuration, And in the locked configuration, at least one locking region (24A, 24B) of the clip can grip the gripping surface (14) of the tube. The clip (22) is placed above a wall of the body (16) which is provided with at least one transverse slot (30A, 30B) through which the locking region (24A, 24B) passes when the clip is in the locking configuration. The slot protrudes into the body and at the end of the slot is provided with at least one blocking element (32A, 32B; 36A, 36B), the bottom of which, in order for the clip to pass from its locked configuration into its unlocked configuration, The part forms the unlocking slope (34A, 34B; 38A, 38B) on which the unlocking area (35A, 35B; 37A, 37B) can slide. The width of the unlocking area is greater than both the width of the locking area and the width of the slot, but less than or equal to the width of the blocking element, said width being measured axially.

Description

technical field [0001] The present invention relates to a quick-connect fitting adapted to be mounted axially on a pipe having a substantially radial gripping surface remote from its free end, the fitting comprising: adapted to cooperate with a sealing device to establish A main body in sealing connection with the pipe, and a locking clip retained axially relative to the main body and having at least one locking region, the clip being initiated in a locking configuration and adapted to engage the pipe in this locking configuration for retaining said pipe The gripping surface of the tube cooperates and the clip is adapted to deform to work in the unlocking configuration. Background technique [0002] Quick-connect fittings of this type are known, for example, from EP 0911565 and WO 02 / 08656. [0003] In this type of joint, the locking clip, also called "locking ring", has an oval shape and is placed inside the body of the joint, the wall of which is provided with openings, a...
