Patent ID: 8713771

Claim:
An apparatus for use in the assembly of an elastic sealing element on an electrical conductor, comprising: a first pin which performs a reciprocating movement and at the front end of which is formed a cutting tip which, on penetration through the elastic sealing element positioned in front of the cutting tip in the direction of reciprocation, produces a through-opening in the elastic sealing element; and a second pin distinct from said first pin for receiving the elastic sealing element which has been provided with the through-opening by the first pin, wherein the first pin is external to the second pin, wherein an outer circumference of the second pin in at least one region is larger than an outer circumference of the first pin for expansion of the through-opening produced in the elastic sealing element and wherein the first pin is surrounded by a hollow cylinder, the first pin and the hollow cylinder being slideable relative to each other to perform a relative movement, so that a front end of the hollow cylinder comes into abutment with the elastic sealing element and slides the elastic sealing element completely over the second pin.
