PCT No. PCT/GB94/00070 Sec. 371 Date Jul. 11, 1995 Sec. 102(e) Date Jul. 11, 1995 PCT Filed Jan. 13, 1994 PCT Pub. No. WO94/16485 PCT Pub. Date Jul. 21, 1994An electric cable joint is enclosed within a heat shrinkable sleeve. The joint region is sealed against the ingress of moisture by a material made of a non-crystalline polymer whose glass transition temperature is less than -40 DEG C. Further, the material has a viscosity at 35 DEG C. of less than 106 Pa-sec and a viscosity at 95 DEG C. of greater than 103 Pa-sec (both viscosities measured at a shear rate of 0.02 sec-1) and a minimum tack value of about 140 gm/cm2.
