Abstract: A system (100) for attaching devices of subsea equipment to a line (10) comprising a line holding mechanism (11,110) and a line holding unit (404). The line holding unit (404) comprises a 5 longitudinal slit (403) for receiving the line (10), multiple gripping elements (13,130,230), and at least one resilient element (12,120,220), related to one subsea device. The resilient element(s) is/are configured to force the multiple gripping elements (13; 130,230) in a direction towards the line (10), whereby the line holding unit (404) is locked to the line (10) in a locking position. By the invention an improved latching device and an accompanying system for attaching and 10 detaching subsea equipment to and from a line is obtained.
