In particular, the irrigation system can be coupled to the at least one irrigation device in terms of fluid technology. The irrigation system can in particular include at least one irrigation device. The at least one irrigation device can in particular be configured as a manual irrigation device (e.g., as a garden hose or a garden sprinkler) or as an at least semi-automatic irrigation device (e.g., as an automatic irrigation device, an artificial rainfall device, a lawn sprinkler, etc.). Preferably, the irrigation system is designed for use with at least one at least semi-automatic irrigation device, in particular for implementing time-controlled irrigation. "Designed" is to be understood in particular as being specially equipped and / or specially set. "Set" is to be understood in particular as being specially programmed and / or specially designed. "An object is designed or set for a certain function" is to be understood as meaning that the object fulfills and / or performs the certain function in at least one application and / or operating state.

[0007] At least one pipeline element is preferably configured as a hose, in particular as a garden hose, a garden hose adapter, a pipe or other pipeline elements that seem meaningful to a person skilled in the art.

[0048] The irrigation system 10a is preferably configured as a garden irrigation system, in particular, for use in a garden environment (e.g., a private garden, a public garden or a park, agricultural land, etc.). The irrigation system 10a is in particular configured for direct and / or indirect irrigation of plants, in particular cash crops, ornamental plants and / or lawns. The irrigation system 10a is in particular configured for conveying a fluid 14a that is not subjected to pressure other than the ambient air pressure.
