Abstract

A connector for smooth pipes characterized by having one of the ends of the sleeve (3) equipped with a peripheral housing (4) receiving locking rings for fixing the connector securely on one end (1) only of one of the pipes to be connected, the end of the other pipe (2) being able to slide freely in the sleeve (3) while being in contact only with the corresponding lip (15) of the joint (13).

Claims

1. Connector for smooth pipes receiving a pressurized fluid, which connector is fixed on the end of one pipe by gripping, and wherein the connector receives freely the end of the other pipe, the connector comprising:

an outer sleeve forming a chamber receiving a seal defining a joint in the form of a resilient sleeve terminating at each end in a lip pressing in a leak proof manner at the end of each pipe through the action of the pressure of the fluid in the pipes,

the outer sleeve forming also a peripheral housing receiving a locking means consisting of two loose open rings, and means in said housing and open rings to position said rings in opposing inclined positions within said peripheral housing, said two loose open rings embed and apply opposite action for affixing the connector securely on one end only of one of the pipes to be connected, the end of the other pipe being able to slide freely in the sleeve while being in contact only with the corresponding lip of the joint.

2. Connector according to claim 1, wherein said means to position said rings includes oppositely inclined walls and a third loose open ring member positioned between said two loose open rings, said third loose open ring member retains each of said two loose open rings against its respective inclined wall of said peripheral housing.
