A RIGID JOINT ASSEMBLY

The present invention relates to a rigid joint assembly (1) for jointing two cables (10; 110). The assembly comprises outer cable entry parts (33; 133) outside a water-tight casing assembly (30). A first and second cable insulation system deformation preventing devices (40; 140) are provided, each comprising a rigid pipe (41; 141), which surrounds a respective first or second cable core end section (12; 112), and a bedding material layer (45; 145), which extends at least partially along a length of an inner surface of the respective rigid pipe (41; 141). The assembly further comprises first and second grooved pipes (51; 151) of elastic material comprising a plurality of grooves (53; 153) on the side facing the cable, each grooved pipe (51; 151) surrounding the respective first or second cable core end section (12; 112) at a respective inner cable entry part (32; 132) inside the water-tight casing assembly 30.
