Slip connectors help in the vertical movement of studs or any kind of supporting structure without imposing additional axial load on the wall. They are specifically used in cold and hot water systems with maximum temperatures up to 65 degrees.

A slip connector is also provided for swivel chair and other similar seating that has a base, a seat rotatably supported thereon, and a weight actuated height adjustor that engages when the seat is unoccupied (to facilitate adjusting the seat height) and disengages when the seat is occupied (to permit the seat to swivel on the base without affecting the seat height).

The slip connector includes two coupling members, which rotate about a common axis when the seat swivels about the base. A stop mechanism positively interconnects the coupling members, causing them to rotate together when they assume a first, angular relationship.

A spring interconnects the coupling members and biases the same when the seat is unoccupied into a second angular relationship, which is spaced a preselected angular measure from the first angular relationship, such that when the user exits the seat, the seat must be rotated through the preselected angular measure before the seat height can be adjusted, thereby greatly alleviating any unintentional height adjustment.

An internal slip connector is useful for attaching tools or other devices to the inside wall of a conduit. This connector has a mandrel with :

• A head end
• 
  
• A threaded end
• 
  
• A reduced-diameter shaft section (disposed between the head end and the threaded end).
• 
  
• Two abutting slip segments( loosely disposed around the mandrel between the head end0).
• 
  
• An upper extending portion of the threaded end.
• 
  
• A nut threaded onto the mandrel below the slip segments.

When tightened, following insertion of the slip segments into the conduit, the nut causes the slip segments to slide radially outward along an oblique interface between them. Gripping surfaces disposed on the outside of the slip segments are thereby pressed into engagement with the inside wall of the conduit.

The internal slip connector can be used with coiled tubing of various wall thicknesses and is easily released after loosening the threaded nut.
