Trash holding cable connecting device and trash holding cable with same

The utility model relates to the technical field of trash holding devices, in particular to a trash holding cable connecting device and a trash holding cable with the same. The trash holding cable connecting device comprises a pair of connecting structures connected with the ends, close to each other, of the two trash holding cables respectively; and the pair of magnetic parts are respectively mounted at the ends, close to each other, of the pair of connecting structures, and have a first state of disconnecting when the impact force is greater than a preset value and a second state of attracting each other when the impact force is not greater than the preset value. The two trash holding cables are connected through the pair of magnetic parts, when the upstream water flow is increased, theimpact force of the water flow on the trash holding cables is increased, the pull force between the two trash holding cables is increased, when the water flow is increased to exceed a preset value, the impact force borne by t
