ABSTRACT:
A connector, particularly for a suspended load, consists of a roundsling including a fibre bundle surrounded by a sleeve and at least one coupling member associated therewith, which comprises a substantially U-shaped U-bolt, into which the roundsling is in-hung, and a releasable bridge member which extends crosswise with respect to the in-hung roundsling and by means of which the shanks of the U-bolt are connected with each other. To harmonize the lifting capability of the connector and that of the roundsling and to obviate overloading of those fibres of the roundsling which are subjected to the greatest tension when the roundsling is loaded the cross section of at least that part of the circumferential area or peripheral surface of the coupling member which is engaged by the roundsling at normal load (the contact surface) has a radius r.sub.b of curvature which satisfies at least one of the conditions
