There are two types of locking feature found on Heim spherical ball joints. One is a safety pin like a diaper pin inserted through a hole in the release bar that prevents it from being depressed to release the joint.

Do these have anything to do with Heim per a previous posting?

I've always seen them referenced by the German names - with this example from a Schempp-Hirth FAA AD

This document clarifies information in Airworthiness Directive (AD) 97-08-06 that applies to Louis L'Hotellier S.A. (L'Hotellier) ball and swivel joint quick connectors installed on gliders and sailplanes that are not equipped with a "Uerling" sleeve or an LS-safety sleeve.

Being a sailplane pilot also, I've always referred to them as L'Hotellier connectors. I was just adding the pics to help with Steve's word description of the safeties used on spherical ball connectors he refers to in Posts #2 and #10.

Here is a good description of the different types of safeties used on the L'Hotellier connectors:
