DEVICE FOR QUICK CONNECTION OF A TUBE TO A RIGID ELEMENT |
摘要 |
The invention concerns a device for the quick connection of a tube (40) to a rigid element (30), comprising a tubular insert (1) having externally means (2) for being fixed into a bore (34) of the rigid element and internally means for axially blocking the tube relative to the insert (1) countering at least the extraction of the tube. The axial blocking means comprise: a shoulder (10) arranged in the tubular insert (1), facing the rigid element (30); a groove arranged in the tube and having a support flank (42) facing the opposite direction at the tube end; a tubular sleeve (12) set between the tube (40) and the tubular insert (1) inner surface, whereof at least an axial section designed to penetrate into the tube (40) groove is capable of elastic radial deformation as the tube end passes through when it is introduced in the insert (1) and constitutes a shape-retaining obstacle preventing the flank (42) and the shoulder (10) from coming together axially in the presence of a force urging the tube (40) and the insert (1) axially apart.
