Claims
- 1. A connector comprising an elongate member having an axial groove formed at an outer circumference thereof in a longitudinal direction and a pipe-like part fitted to said groove with one end thereof being opened at a first end of said elongate member and the other end of said pipe-like part being extended from a second end of said elongate member wherein the pipe-like part fits within said groove so that the pipe-like part fits within the outer circumference of said elongate member and said connector further comprising a plurality of spike like protrusions originating at said first end of said elongate member wherein said spike like protrusions engage the bottom of a bore hole and thereby provide a space between the bottom of said bore hole and said first end thereby facilitating flow of an adhesive from said from said pipe-like part, said spike like protrusions further impeding the ability of said connector to rotate in said bore hole.
- 2. A connector as set forth in claim 1 in which a pipe-like branch pipe is removably inserted into one opening of said pipe-like part.
- 3. A connector as set forth in claim 1 in which at least one of said ends of said elongate member is further formed with an adhesive agent guiding groove wherein said adhesive agent groove is thereby formed transaxial to said elongate member.
- 4. A connector as set forth in claim 3 in which said adhesive agent guiding groove of said elongate member is communicated with said axial groove of said elongate member and an opening of at least one end of said pipe-like part is opened at said adhesive agent guiding groove.
- 5. A connector as set forth in claim 1 in which the pipe-like part fitted to said axial groove is fixed to said elongate member by welding or with adhesive agent.
- 6. A connector as set forth in claim 1 in which an outer circumferential surface of said elongate member is formed with a concave or convex part.
