Support tube for a cold-shrink sleeve for joining electric cables

Abstract

The invention relates to a support tube for a shrink sleeve for an electric cable joint, the tube serving to support a sleeve in an expanded state and then to be removed so as to allow the sleeve to shrink onto the joint. According to the invention, the support tube is constituted by an open tube fitted on its two longitudinal edges with mutual engagement means.

1 . A shrink-sleeve support tube comprising: 
 an open tube fitted on its two longitudinal edges with mutual engagement means, said open tube for supporting, in an expanded state, a sleeve for an electric cable joint, and then for being removed so as to allow the sleeve to shrink onto the joint.    
   
   
       2 . A support tube according to  claim 1 , wherein said engagement means are distributed regularly along said longitudinal edges.  
   
   
       3 . A support tube according to  claim 1 , wherein said engagement means are constituted by snap-fastening teeth.  
   
   
       4 . A support tube according to  claim 1 , wherein said longitudinal edges are constituted by mutual engagement tongues of thickness substantially equal to half the total thickness of the tube.  
   
   
       5 . A support tube according to  claim 4 , wherein said mutual engagement tongues on an edge alternate between being internal tongues and external tongues.  
   
   
       6 . A support tube according to  claim 4 , wherein said engagement means are constituted by snap-fastening teeth that are disposed on the contacting faces of some of said tongues.
