## Abstract

A well connector connectable to the outside of coil tubing for coupling the tubing to another member. The connector includes a tubular body externally enclosing the end of the coil tubing and a second end for connection to another member. A slip housing is threadably connected to the first end of the body and encloses slips between the body and the housing for gripping the outside of coil tubing. The body includes a thermally compensated packing element and a threaded actuation energizer is provided threadably engaging the body, separate from the slip actuation, for energizing the packer element into a seating engagement with the exterior of the coiled tubing.

## Claims

### Claim 1

A well connector connectable to the outside of one end of well coiled tubing for coupling the coiled tubing to another member comprising,
a tubular body having first and second ends, the first end sized to externally enclose the one end of the coiled tubing, said second end including connecting means for connecting to the other member,
a slip housing connected to the first end of the body,
slip means positioned in the slip housing and engagable with the first end of the body and positioned to engage and grip the outside of the coiled tubing on movement of the slip housing and the first end of the body together for actuation of the slips,
actuating means for moving the slip housing and the first end of the body together for actuation of the slips,
said tubular body including a packing element positioned to engage the exterior of the coiled tubing, said packing element spaced out of contact with the slip means, and
threaded actuated energizing means threadably engaging the body, separate from the slip actuating means, for energizing the packing element into a sealing engagement with the exterior of the coiled tubing.

### Claim 2 (depends on 1)

The connector of claim 1 wherein the body includes a wall transverse to the longitudinal axis of the body and positioned adjacent the packing element and a plurality of elements extending perpendicularly through the wall and positioned between the threaded actuated energizing means and the packing element.

### Claim 3 (depends on 2)

The connector of claim 2 wherein the elements are pins.

### Claim 4 (depends on 2)

The connector of claim 2 wherein the elements are arcuate in cross section.

### Claim 5 (depends on 1)

The connector of claim 1 including,
a thrust washer positioned adjacent the packing element,
said threaded actuated energizing means extending through the body and engaging the thrust washer for pressing the thrust washer against the packing element.

### Claim 6 (depends on 5)

The connector of claim 5 wherein the energizing means includes threaded screws extending perpendicularly to the longitudinal axis of the body.

### Claim 7 (depends on 1)

The connector of claim 1 wherein the body includes first and second parts threadably connected together, with the packing element therebetween, forming an energizer means for setting the packer element.

### Claim 8 (depends on 1)

The connector of claim 1 wherein the threads connecting the slip housing to the body and the threads connecting the energizing means to the body are identical.

### Claim 9 (depends on 1)

The connector of claim 1 including thermal compensating means positioned adjacent the packer element.
