FIELD: hose-type cables including those used in mines. SUBSTANCE: insertion box has flexible safety hose 1 carrying conducting cores 2 with its end clamped between surrounding compression bushing 4 and internal supporting bushing 8 to ensure tight joint and desired rupture strength; connecting sleeve 5 abutting against compression bushing 4 with insert 6 inserted therein that carries contact members 13 electrically connected to conducting cores 2. Novelty is that compression bushing 4 is built integral with connecting sleeve 5 to form single junction box 3 that may be joined to insert carrying contact members 13 by means of latching joint 15, 16 ensuring desired rupture strength. EFFECT: simplified design, facilitated installation, and relatively low cost of insertion box claimed. 23 cl, 4 dwg
