ABSTRACT:
A fastener is disclosed for attaching first and second members. The fastener includes a longitudinal shaft portion having first and second segments each having a cross-sectional shape substantially conforming to the peripheral shape of first and second openings formed in the respective members. The longitudinal length of each segment substantially conforms to the depth of said first and second openings. A cap member is formed at a first end of the shaft portion adjacent and outside the first segment. The cap member is larger than the periphery of the first opening. A spacer member is formed on the shaft portion between the first and second segments. This spacer member has an outer periphery larger than the first and second openings to inhibit passage therethrough so as to secure the first member on the first segment of the shaft portion between the cap member and the spacer member. The fastener also includes an abutment member positioned on the second end of the shaft portion outside of the second segment. The abutment member has an outer periphery larger than the second opening to inhibit passage of the abutment member therethrough, thereby securing the second member on the second segment of the shaft portion of the fastener. The spacer member and abutment member each have at least one slot formed therein to permit circumferential compression so as to allow passage of the spacer member and the abutment member through the first and second openings, respectively.
