Abstract: There is disclosed a connector consisting of a male coupler having a shank and head member and a female coupler including a cylindrical member having a bore and being open at one end for receiving the shank of the male coupling member. The female coupler is also provided with a head member affixed to the cylindrical member at the end opposite the open end. Both head members define a flat outer and inner face. The shank of the male coupler is preferably threaded for engaging corresponding mating threads or for self-tapping threads in the bore of the female coupler for retaining the shank in the bore. The female coupler, which is normally positioned at the upper surface of the surfboard, is provided with a head member having an axially extending opening which communicates between the outer surface of the head member and the bore and a normally extending passage which communicates between the bore and the exterior of the cylindrical member.
