Presented herein is a connector forming a joint between first and second surfaces. The connector includes a hollow male member embedded in a first surface. The male member has open ended protrusion extending therefrom. A hollow female member to be embedded in second surface. The female member has a mating opening for receiving the protrusion and a flexible sealing means for forming a fluid tight seal between the female and male members. When installed, a tendon forms part of the first surface and extends through protrusion into female member. Prior to grouting, movement of the tendon during settling of first surface is facilitated by the male and female member, without breaking the fluid tight seal formed by flexible sealing means. Also presented is a method of forming a joint between a vertical surface and a horizontal surface.
