Bolt holding device and connecting system

A bolt holding device (30) for mounting a bolt, said bolt holding device comprising:

• an insert sleeve (41) comprising a spring seat section (55), a securing section (56), and a transition area (59) between the spring seat section and the securing section;
• a spring energy store (122) disposed within the spring seat section;
• a retaining arrangement (85) disposed within the insert sleeve opposite the spring energy store, the retaining arrangement (85) comprising at least one pull-out prevention element (95) on an outer periphery thereof;
• a clamping disc (131) disposed within the retaining arrangement, and comprising at least one clamping element (133) on an inner periphery thereof;
• and
• a stop lid (101), disposed inside the retaining arrangement and supporting the clamping disc (131);
• wherein the bolt holding device (30) is moveable between:
• an unlocked configuration wherein the retaining arrangement (85) is partially within the spring seat section (55) of the insert sleeve (41), and the at least one pull-out prevention element (95) is deflected inward, and
• a locked configuration wherein, when a bolt (20) is inserted into the insert sleeve (41) in a bolt insert direction (31) such that the bolt (20) engages the at least one clamping element (133) of the clamping disc (131), the retaining arrangement (85) is moved into the securing section (56) of the insert sleeve (41) such that when the at least one pull-out prevention element (95) moves past the transition area (59), the pull-out prevention element (95) is allowed to move outwardly, and movement of the bolt (30) in a direction opposite the bolt insert direction (31) is blocked.
