The inventors disclose and teach herein a device that quickly and reliably attaches rigging to a fishing line, especially trolling lines. The device includes a spring-loaded clip with means for attaching additional accessories to the clip, such as weights. Accordingly, in the context of trolling, a trolling depth can be set and readjusted rapidly simply by clipping different weights onto the line. Moreover, the clip includes a side-opening for receiving a fishing line in compression between a spring-loaded plunger and anvil. The line is further secured by an embossed retainer blocking the line from slipping out from between the plunger and anvil.
