Patent attributes
An electrical plug connector including two mating connectors. A first plug section includes a receiving sleeve which encircles the first coupling section and which carries a locking element which includes flexible tabs movable between a locking position and an unlocking position and which are pre-stressed in its locking position. Held displaceably on the receiving sleeve is a sliding or release sleeve which may be manually moved axially to engage the locking element and release the mating connector. The second plug section has a plug tube which surrounds the second coupling section. When the plug tube is inserted in the receiving sleeve, the locking element rests on the outside of the plug tube in its locking position whereby the plug sections are connected. The connectors can be released by actuating the sliding sleeve to move the locking element into its unlocking position.
