The swivel connector permits two links, such as cables, chains, etc. to be quickly connected and disconnected without use of tools, and can pass over pulleys and through fairleads etc. The connector has a plug connector portion which has head and neck portions which are received in a complementary recess of a socket connector portion. The socket connector portion comprises second and third body members each having a longitudinally aligned main face with a recess generally complementary to one half of the neck and head portions. The connector portions have bearing surfaces which generate inwards forces on the second and third body members which tend to hold the second and third body members together so as to embrace the first body member. A resilient structure applies an outwardly directed axial force between the connector portions, which tends to force the main faces and bearing surfaces into engagement so as to initiate and enhance gripping of the two portions together. The connector portions are simple to manufacture and maintain, and when coupled together resist intrusion of foreign matter, such as dirt, etc., thus reducing wear from abrasive particles.

A swivel connector comprising: (a) a plug connector portion having a first body member having an outer portion, a neck portion and a head portion, the outer portion having an eye to receive a first link, the neck portion having a diameter less than the head portion and being concentric therewith about a longitudinal axis to provide a shoulder having a first bearing surface, (b) a socket connector portion having second and third body members, each body member having a longitudinally aligned main face having a recess which is generally complementary to one half of the neck and head portions of the first body member to accept the said one half therein, each recess having a semi-annular bearing surface positioned to engage a corresponding half of the first bearing surface of the first body member when the main faces of the second and third body members are abutted to form a unit to enclose the neck and head portions of the first body member, the second and third body members each having a respective outer portion with a respective eye so that when the second and third body portions cooperate with each other as the said unit, the eyes thereof are aligned with each other to receive a second link passed therethrough, (c) force generating means on at least one bearing surface for generating an inwards force on the second and third body members, which force is directed towards the longitudinal axis and tends to hold the second and third body members together, (d) resilient means for applying an initiating force between the connector portions so as to force the complementary bearing surfaces into engagement with each other to generate the said inwards force.
