A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a main body and a side frame member provided on each lateral side of the main body. The main body provides an orifice therethrough for the introduction of breathable gas into a nasal breathing cavity and a collar that substantially surrounds the orifice. At least one of the side frame members includes an integrally formed locking clip receiver assembly. The frame is formed by molding such that mold components of a mold can be withdrawn along a single plane to separate the mold from the collar and the locking clip receiver assembly.

1. A respiratory mask assembly for delivering breathable gas to a patient, comprising: a frame having a main body and a side frame member provided on each lateral side of the main body,the main body providing an orifice therethrough for the introduction of breathable gas into a nasal breathing cavity and a collar that substantially surrounds the orifice,at least one of the side frame members including an integrally formed locking clip receiver assembly,wherein the frame is formed by molding such that mold components of a mold can be withdrawn along a single plane to separate the mold from the collar and the locking clip receiver assembly,wherein the locking clip receiver assembly includes a slot adapted to receive a locking clip, the slot having a central portion and two locking portions on opposite sides of the central portion, andwherein the central portion has a lower central portion surface and each of the two locking portions has a lower locking portion surface, and a junction between the lower central portion surface and each lower locking portion surface is arranged to include a stepped configuration, and the stepped configuration is angled to enable the mold components to be withdrawn along the single plane. 2. The respiratory mask assembly according to claim 1, further comprising an elbow assembly adapted to be coupled to the collar. 3. The respiratory mask assembly according to claim 1, wherein the slot extends generally horizontally so as to enable the mold components to be withdrawn horizontally. 4. The respiratory mask assembly according to claim 1, wherein the locking clip includes a main body providing a front portion and a rear portion, the front portion adapted to be removably coupled with the locking clip receiver assembly and the rear portion adapted to be removably coupled to a headgear assembly. 5. The respiratory mask assembly according to claim 4, wherein the front portion and the rear portion are disposed at an angle β to one another, and the front portion is generally horizontally aligned. 6. The respiratory mask assembly according to claim 4, wherein the slot extends generally horizontally and adapted to receive the front portion of the locking clip. 7. The respiratory mask assembly according to claim 4, wherein the rear portion of the locking clip includes a cross bar that forms an opening through which a strap of the headgear assembly can pass and be removably coupled with the cross bar, and the front portion of the locking clip includes at least one resiliently flexible spring arm that is flexible within a plane of the main body. 8. The respiratory mask assembly according to claim 1, wherein the collar has a rim which extends horizontally and radially from the orifice. 9. The respiratory mask assembly according to claim 1, wherein the central portion includes a wall that extends upwardly from the lower central portion surface. 10. The respiratory mask assembly according to claim 1, wherein the central portion has an upper central portion surface that is continuous with an upper locking portion surface of each of the two locking portions. 11. The respiratory mask assembly according to claim 1, wherein the central portion of the slot includes a height that is greater than a height of each of the two locking portions of the slot. 12. The respiratory mask assembly according to claim 1, wherein the slot includes a front opening, and the lower central portion surface and each lower locking portion surface extends rearwardly from the front opening into an interior of the slot. 13. The respiratory mask assembly according to claim 1, wherein the stepped configuration is angled in relation to a direction of insertion of the locking clip into the slot. 14. A method for molding a frame for a respiratory mask assembly, the method comprising: molding a frame in a mold to include a main body and a side frame member provided on each lateral side of the main body, the main body defining an orifice therethrough and a collar that substantially surrounds the orifice;forming a locking clip receiver assembly on at least one of the side frame members; andwithdrawing opposed mold components of the mold along a single plane to separate the mold from the collar and the locking clip receiver assembly,wherein the locking clip receiver assembly includes a slot adapted to receive a locking clip, the slot having a central portion and two locking portions on opposite sides of the central portion, andwherein the central portion has a lower central portion surface and each of the two locking portions has a lower locking portion surface, and a junction between the lower central portion surface and each lower locking portion surface is arranged to include a stepped configuration, and the stepped configuration is angled to enable the mold components to be withdrawn along the single plane. 15. The method according to claim 14, wherein the collar is adapted to receive an elbow assembly. 16. The method according to claim 14, wherein the slot extends generally horizontally so as to enable the mold components to be withdrawn horizontally. 17. The method according to claim 14, wherein the locking clip receiver is adapted to be removably coupled to a front portion of the locking clip. 18. The method according to claim 14, wherein the collar has a rim which extends horizontally and radially from the orifice. 19. The method according to claim 14, wherein the central portion includes a wall that extends upwardly from the lower central portion surface.
