ABSTRACT:
A swivelable connector for tubular conduits comprising first and second mutually insertable tubular connector members and a retainer for retaining the second tubular connector member in the first tubular connector member. The retainer comprises engaging members positionable around the second tubular connector member and in the first tubular connector member, urging members engageable with the outer surfaces of the engaging members along a relatively axial movement between the urging members and the engaging members, to radially urge the engaging members into engagement with the second tubular connector member. The urging members can be embodied by a stepped inner surface of the first tubular connector member associating with the movable engaging members, or by the movable urging members associating with the fixed engaging members.
