Claims
- 1. An adapter insertable into the open end of a tube to modify the same to matingly receive the externally-threaded portion of a member, said tube being provided with an opening therethrough, said adapter comprising:
- a first section having an end surface;
- a second section having an end surface;
- each of said sections having a substantially semi-cylindrical inner surface provided with cooperative internally-threaded recess segments, having an outer surface simulating half of the cross-sectional shape of said tube, and having longitudinal surfaces joining said inner, outer and end surfaces;
- at least one flexible web joining said section end surfaces;
- said first section being arranged to be folded through an arc of approximately 180 degrees to overlie said second section through compliant flexure of said web such that said section longitudinal surfaces will be arranged to face one another to form an adapter having an internally-threaded recess and an external surface simulating the cross-sectional shape of said tube;
- one of said sections being provided with a lug arranged to be received in said tube opening when said adapter is inserted into said tube to prevent unintended withdrawal of said adapter from said tube;
- whereby said adapter may be inserted into said tube to modify the same to matingly receive the externally-threaded portion of a member.
- 2. The adapter as set forth in claim 1 wherein one of said sections is provided with a recess extending into said section from one of its longitudinal surfaces, and wherein the other of said sections is provided with a pin extending outwardly from one of its longitudinal surfaces, said recess being adapted to receive said pin to align said internally-threaded recess segments when said sections are folded together.
- 3. The adapter as set forth in claim 1 wherein said longitudinal surfaces have opposing end portions separated by a clearance when said sections are superimposed which permits these sections at said clearance to be collapsed to reduce the transverse dimension of said adapter for insertion into said tube.
