ABSTRACT:
A connector of frangible material for mounting on the piercing end of a nail-like fastener, connects the fastener to a bracket or clamp. The bracket has a conical frustrum-shaped aperture. The connector has a conical frustrum-shaped leading end that fits into the conical frustrum-shaped aperture in the bracket. The trailing end of the connector grips the fastener. The connector locks to the bracket by passing its trailing end through the leading opening of the conical frustrum-shaped aperture and snugging the conical frustrum leading end of the connector into the conical frustrum-shaped aperture in the bracket.
