Abstract
A connecting lock for tire chains, comprising an elongate receiving opening for receiving two chain links, framed by a first longitudinal crosspiece, an opposed, a second longitudinal crosspiece interrupted by an insertion opening, and two transverse crosspieces. The chain links in the receiving opening are secured from sliding out by means of a closing bolt, which can be inserted via one end into a blind bore in the first longitudinal crosspiece. A threaded bore leads in the first longitudinal crosspiece to the blind bore, starting from a side face. A spring pressure piece is screwed into the threaded bore. A spring-loaded detent part of said spring pressure piece is directed into the blind bore. When the closing bolt is inserted into the blind bore, the spring-loaded detent is latched into a recess in the periphery of said closing bolt.
