An exemplary bulkhead connector assembly may include a housing that has an inner diameter surface, a first opening and a second opening. The assembly may further have a retainer attached to the housing and one or more feet extending radially inward from the inner diameter surface of the housing. The assembly can also include a collar that has a portion received within the first opening or the second opening. The collar may have an outer surface that cooperates with the feet of the retainer to hold a conduit within the housing.

A push type conduit joint release structure is provided, and relates to the field of conduits. The push type conduit joint release structure includes a tubular main body. The main body is internally provided with a gear ring and a propeller. The gear ring includes an outer ring with a first notch, and a plurality of teeth slantly protrude towards an axial direction of the outer ring on an inner wall of the outer ring. An inner circumferential wall of the main body is concave at the position of the gear ring to form a limit ring groove. When the gear ring is located inside the limit ring groove, the teeth protrude out of an inner circumferential wall of the propeller. The push type conduit joint release structure has the advantages of reducing the quantity of fittings, promoting the structural stability and improving the clamping force for a conduit.

A unit for connecting a fluid line to a port of a superordinate assembly, comprising a base body comprising a connection piece at one axial end for connection to the fluid line and a receiving portion at another axial end. The unit comprises an insert element comprising a resilient material and at least one radially outwardly projecting protrusion. The insert element defines, in its interior, an axial central connection opening and is separate from and connectable to the base body. The at least one protrusion projects into a corresponding aperture formed in an area of the receiving portion. Each protrusion comprises a blocking flank extending outwardly in a substantially radial direction and facing the axial end of the base body opposite the connection piece. The blocking flank is configured to abut against a respective blocking protrusion on the base body in a receiving portion engaged state of the insert element.
