The vent hose cap includes a base and a head. The base includes cylindrical walls and partially cylindrical interior skirt sections. The interior of the skirt sections form an aperture for receiving a vent hose, while the space defined between the cylindrical walls and the skirt sections, including the gaps between the skirt sections, define a longitudinal gas passageway. Radial slots formed in the base provide gas communication from the interior of the gas vent hose to the longitudinal gas passageway. The cap includes a barbed shaft with an H-shaped cross-section for insertion into the base and through the interior of the vent hose.

1. A vent hose cap including: a base including outer walls, a passageway formed inwardly from said outer walls, an aperture formed inwardly from said passageway for engaging a hose, a gas communication path formed from said aperture to said passageway, and an opening formed along a common axis with said aperture; and a head including a shaft for insertion through said opening and into the hose engaged by said base. 2. The vent hose cap of claim 1 wherein said opening joins said aperture, said opening being smaller than said aperture thereby forming a circular ledge which acts as a stop for the hose. 3. The vent hose cap of claim 2 wherein said outer walls are cylindrical and wherein said passageway is separated from said aperture by an at least partially cylindrical interior skirt. 4. The vent hose cap of claim 3 wherein said at least partially cylindrical interior skirt is formed of cylindrical sections with circumferential gaps therebetween, said circumferential gaps forming at least part of said gas communication path. 5. The vent hose cap of claim 4 wherein said head includes a seal which is urged against said base, thereby preventing a gas communication path from forming through said opening. 6. The vent hose cap of claim 5 wherein said head includes a first detent element and said base includes a second detent element, said first detent element engaging said second detent element in an installed position of the vent hose cap. 7. The vent hose cap of claim 6 wherein said first detent element includes a detent depression formed in said head and said second detent element includes a tab rising from said base and terminating in a detent prong which engages said detent depression. 8. The vent hose cap of claim 7 wherein said shaft includes barbs for engaging the hose. 9. The vent hose cap of claim 8 wherein said shaft has a H-shaped cross section with a cross member separating two partially circumferential members, said barbs being formed on said partially circumferential members and said gas communication path including a space between said partially circumferential members. 10. The vent hose cap of claim 9 wherein said base and said head are contemporaneously molded as a single piece and said shaft of said head is inserted through said opening prior to use of the vent hose cap.
