When your garden hose is in trouble, you can either fix it or recycle it. Patch couplings as well as quick coupling adapters are readily available. Magic Wrap is a rubber tape that effectively seals holes permanently in hoses. Just remember to not use it like a tape, but to stretch it twice its original length while wrapping, it will pull itself back and literally seal to itself as one solid rubber mass.
And if all else fails -- drill a lot more holes in the hose, put a cap on the end (water bottle caps generally work) and you have a brand new sprinkler. Experiment with hole size and placement to vary your sprinkler from a slow soaker (large holes) to a high sprayer (fewer and smaller holes).
Magic Wrap is available just about anywhere.
