Abstract: A plug connector includes a housing, a locking element and a verification element. The housing has a receiving chamber, a connection piece and a duct through which fluid can flow. The locking element is movable between an open position and a fastening position, a plug can be inserted in the receiving chamber in the open position of the locking element, and a plug inserted in the receiving chamber can be fastened within the receiving chamber via the locking element in the fastening position of the locking element. In an open position of the locking element, the verification element is at least partially covered by the locking element, and in a fastening position of the locking element, the verification element can be read.

Abstract: A quick connector including a female part with a stepped bore arranged to receive an endpiece and a collar of a male part, and a latch including a ring in a housing arranged in the female part to slide radially between an eccentric position and a position coaxial with the bore, and the latch including a latching indicator mounted to slide radially in the ring between two indication positions, and at least one blocking member for blocking the indicator in a first indication position, the blocking member being movable between an indicator-blocking position and a retracted release position, and having a contact portion projecting into the female portion beyond the latch to co-operate with the collar in such a manner that the collar takes the blocking member into its release position when the male part is inserted into the female part.
