Embodiment Construction

[0013] The joint shown in the figures comprises a container shell 1 and a retaining spring 2 made of hard disintegrable plastic material. A tube 3 can be inserted into the joint, and the tube 3 has an annular locking ring 4 . The tube 3 may comprise the end of a conduit made of rigid material or a rigid fitting which may be connected by conventional means to the end of a pipe made of softer material.

[0014] According to attached Figure 4 , The container shell 1 consists of a cylindrical shell wall 5 and a small chamber 6 for receiving an insert comprising several shoulders. Each shoulder forms a limited stop 8 at the end of the chamber 6 . A cylindrical fitting 7 forms the axial extension of the chamber for connecting fluid lines (not shown in the figures). The chamber 6 starts from a first area 6', the inner diameter of which corresponds to the outer diameter of the tube 3. The second area 6" has a larger diameter and is adjacent to the first area. The larger diam...

Abstract

A plug in connector of detachable type used for inserting into tubular plug in piece consists of stop spring with pliers for clamping up locking ring of tube and shell. It is featured as opening pliers to let locking ring pass pliers and closing pliers when tube is completely inserted in then engaging pliers with locking ring, extending a support piece towards outside from pliers, making said support piece be with arc shaped surface for increasing retention of support piece.

Description

technical field [0001] The invention relates to a joint for inserting a pipe with a locking ring. Background technique [0002] The invention relates to a joint for inserting a pipe with a locking ring. The insertion tube may be the end of a durable metal tube, such as that used for fuel lines. However, the couplings can also be made of hard plastic material or other commonly used injection molded materials for connection with hose lines or pipes in the usual manner. [0003] In currently used joints, the end faces of the support body have the shape of a circular arc so as to extend radially outwards to the axis of the housing. When a tensile force is applied to the tube, the end face of the support body abuts the inner surface of the recess in the case of the opening with the end face. In the practical application of the present fitting, it has generally been found that the holding force produced in this way is not sufficient to ensure a reliable connection of the fuel l...
