Abstract: A leakproof coupling means for use in connecting garden hoses and other conduit members which have cooperatively engageable male and female coupling members each having an end surface and each having a shoulder formed therein at a location spaced from the respective end surfaces, and a resilient tubular member of a size and shape to fit into the male coupling member, the resilient tubular member having spaced opposite end surfaces adapted to simultaneously sealably engage the respective shoulders formed in the male and female members when the members are coupled together. The present coupling means can be used between connected sections of garden hose and the like and can also be used between a garden hose and a faucet or tap connection therefor. The present device can also be modified to have the hose extend through and beyond one end of one of the coupling members for engagement with means on the other coupling members when the coupling members are connected together.
