Pipe and tubing connector
A connector for pipe or tubing. The connector includes a unitary expansion member, formed from a body, a first expansion leg extending from the body, an optional second expansion leg extending from the body, and at least one opening extending through the body. In use, the connector is fastened in place by a fastener that is inserted through the at least one opening to contact at least one of the first and second expansion legs and force at least one of them to deform and contact the inside of the pipe or tubing, thereby securing the connector within the pipe or tubing.
1. A fastening assembly for connecting two hollow cylindrical handrail sections, each section having a passage there through and a surface hole in communication with each respective passage, the fastening assembly comprising:
a homogenous one-piece connector having a flat rectangular body, and two substantially identical flat rectangular leg portions extending from opposite sides of the body in a common direction perpendicular to the body, each leg portion forming a rounded corner with the body portion, each leg portion connected to a knee portion extending inward over at least a portion of the body and each knee portion connected to a foot portion at an end opposite the knee portion; and
at least one threaded fastener threadably engaged within at least one threaded bore formed in the body of the one-piece connector;
wherein adjustment of the at least one fastener toward the leg portions causes the fastener to engage the knee portions extending over the body and the engagement of the fastener and the knee portions forces the leg portions outward and causes free ends of the foot portions to bear against inner surfaces of each of the handrail sections thereby locking the handrail sections together in alignment in the longitudinal direction.
2. A fastener for connecting two hollow cylindrical handrail sections, each handrail section having a passage there through and a surface hole in communication with the respective passage, the fastener comprising:
a homogenous one-piece connector having a flat rectangular body, and two substantially identical flat rectangular leg portions extending from opposite sides of the body in a common direction perpendicular to the body, each leg portion forming a rounded corner with the body portion and each leg portion connected to a knee portion extending inward over at least a portion of the body, and each knee portion connected to foot portion at a free end opposite the rounded corner and with at least one threaded bore formed in the body of the one-piece connector;
such that, once the one-piece connector may be inserted into the handrail sections and at least one threaded fastener is inserted through one of the surface holes and threadably engaged within at least one threaded bore, adjustment of the fastener toward the knee portions causes the fastener to engage the knee portions extending over the body and the engagement of the fastener and the knee portions forces the knee portions outward and causes the free ends of the foot portions to bear against inner surfaces of each of the handrail sections thereby locking the handrail sections together in alignment in the longitudinal direction.
