Abstract
A snap-fastenable coupling for a low pressure fluid transfer hose, in particular for a motor vehicle, comprises two semicylindrical pieces mounted on a portion of hose made of rubber or the like that is engaged on an insert. The two pieces are fixed together by resilient snap-fastening and they simultaneously secure the hose to the insert in sealed manner. The pieces have elastically deformable front ends enabling them to snap-fasten resiliently onto a peripheral projection of the endpiece.
Claims13
A snap fastenable coupling for a fluid transfer hose, comprising:
- a tubular insert mountable inside a flexible hose, and configured to sealingly mount a tubular endpiece of a fluid circuit;
- and
- a snap-fastening locking part comprising a cylindrical annular portion mountable to the hose to sealingly clamp the hose onto said tubular insert when said tubular insert is mounted inside the flexible hose, said snap-fastening locking part further comprising elastically deformable longitudinal tabs extending from said cylindrical annular portion, and two diametrically opposed semi-annular portions connected to said tabs at positions to engage a peripheral projection of said tubular endpiece when the tubular endpiece is mounted to said tubular insert, thereby holding the tubular endpiece on said insert and locking a connection between the tubular endpiece and the hose.
