Plug-in connector for hydraulic or pneumatic piping systems has elastic device between expansion bush and plug-in device so that expansion bush is longitudinally movable relative to plug-in device against action of elastic device

摘要

The plug-in connector (10) for hydraulic or pneumatic piping systems has a holder (14) or housing with a continuous opening (16) and a plug-in device (12) with a through-opening (18). An expansion bush (30) on the plug-in device has an elastic wall with a locking device (34) in the free end section which fits behind a mating locking device (20) in the holder opening when the plug-in device is fitted in the holder opening. A first elastic device (40) is installed between the expansion bush and plug-in device in such a way that the expansion bush is longitudinally movable relative to the plug-in device against the action of the elastic device.
