It is a moulding integral with a release lever (4), with a housing for the top part of the latter, which swings on a hinge at the bottom. in the top part of the housing is a recess (12a) into which the lever end snaps. At the bottom, there are two symmetrical windows with tongues easily torn free on opening by lifting the lower part of the lever, the top part of the latter bearing against the top of the ring in the sealed position. Once the tongues have been forn free the lever hinges at the level of a second hinge at the height of the tops of the windows.</p> |
