Abstract: A retaining system, in particular for retaining bundles of wires in a telephone exchange, comprises successive stages (E1, E2) each constituted by a hook (B2, S2, 18, 20) which, together with the hook (22) of an adjacent stage (E1) constitutes a loop suitable, for example, for retaining a bundle of electric wires. The first stage (E1) is provided with fixing means (W) for fixing it to a supporting structure. Each subsequent stage (E2) is connected to the preceding stage (E1) by a link rod (T1) which is snap-fastened in housings (L1, L2) in each stage. The invention is applicable to telephone exchanges.

Abstract: A connector for self-stripping insulated electric conductors, said conductor including a fork or clip type conductive connection part with at least two resilient arms between which is provided a slot for inserting the electric conductor to be connected, the connection part being designed for inserting in a cavity in a stand made of insulating material. The double fork type connection part (75) has two inclined slots (64, 65) whose axes converge towards the top of the connector. Application to electric connections, in particular in telecommunications.
