Insertion coupling to connect fluid line to tube has coupling ring part with at least three locking sectors cover ring more than 180 degrees

摘要

The coupling has holding ribs (17) and a tube piece (1) with one end (1a) connected to the fluid line and the other end able to be fitted to the tube, and connected to a coupling ring part (14) by a elastic holding arms (12). The coupling ring part has at least three locking sectors (13) and covers more than 180[deg].
