The TE Connectivity 201921-1 is a locking spring catch from the M series, supplied as a 2-piece kit. It is an accessory — not a connector body — designed to provide a positive locking action when used with M series connector housings. The spring catch engages to prevent accidental unmating in applications where vibration or cable strain is present. This spring catch is intended for use with M series connectors. It fits the locking mechanism of compatible M series plug and receptacle housings, adding a spring-loaded retention feature that supplements the primary latch. No modification to the connector body is required — the catch installs directly into the existing locking slot. ## Kit Contents and Packaging The 201921-1 ships as a 2-piece kit in bulk packaging. Each order unit contains two spring catches, sufficient for one mated pair of connectors. The bulk packaging is standard for accessory kits of this type.","metaTitle":"TE Connectivity 201921-1 M Series Spring Catch, Locking","metaDescription":"TE Connectivity 201921-1 M Series locking spring catch, 2-piece kit.
