The present invention relates to the connections between respiratory humidifiers and/or other such devices and heated breathing conduits used to couple a patient to the humidifier. In particular, the invention is a connector to couple a gases supply means and a conduit, such that the connector causes there to be an electrical and pneumatic, that is, sealed connection between a conduit including an electrical wire extending within, throughout or about it and a gases supply device, such as a humidifier, blower or the like. The connector may be of a single port type or a dual port type. The dual port type connector is suitable for ventilator apparatus that have a dry line (dry breathing conduit) extending from a ventilator or blower that carries dry gas to a humidifier and an inspiratory limb that extends from the humidifier to the patient and carries humidified gases to the patient.

1. A connector for coupling a gases supply to a conduit, where said conduit is of the type that includes electrical wire extending within, throughout or about said conduit, said connector comprising:a female gases passage portion of a generally tubular shape attached in use to one of said gases supply or said conduit, said female portion including a locking connector and an electrical connector, a male gases passage portion of a generally tubular shape attached in use to the other of said gases supply or said conduit, said male gases passage portion including a locking connector receiver and an electrical connector receiver, said male gases passage portion and said female gases passage portion coupled in use to form a pneumatically sealed gases passage between said gases supply and said conduit, said coupling also engaging said electrical connector and said electrical connector receiver, a collar of generally tubular shave on said female portion, said collar capable of being moved over said female gases portion once said male and female gases passage portions are coupled in use, said collar causing said locking connector to engage with said locking connector receiver to releasably lock said male and female portions together. 2. A connector according to claim 1 wherein said collar is capable of being threaded to said female gases passage portion.3. A connector according to claim 1 wherein said locking connector receiver is at least one recess located at the external surface of said male portion, and said locking connector is at least one protrusion on the internal surface of said female gases passage portion, shaped to engage with said at least one recess to enable said releasable locking of said male and female gases passage portions together.4. A connector according to claim 3 wherein said collar is capable of being threaded to said female gases passage portion.5. A connector according to claim 3 wherein said collar causes said at least one protrusion to engage with said recess, said collar including at least one projection that abuts said female gases passage portion and causes said releasable locking of said male and female gases passage portions together.6. A connector according to claim 5 wherein said collar is capable of being threaded to said female gases passage portion.7. A connector according to claim 5 wherein said gases supply is a humidifier.8. A connector according to claim 5 wherein said gases supply is an integrated blower and humidifier.9. A connector according to claim 5 wherein said gases supply is a positive pressure ventilation device.10. A connector according to claim 5 wherein said electrical connector is a protrusion located on the external surface of said male gases passage portion, said protrusion having at least one electrical contact surface and being connected to at least a power supply, and wherein said electrical connector receiver is a port located on the external surface of said female gases passage portion, sized to receive said protrusion, said protrusion making at least one electric contact with said port.11. A connector according to claim 10 wherein said port contains at least one pin, and said protrusion contains at least one elongate recess which in use receives said at least one pin.
