Abstract: A pin comprises a head portion, a shank portion, and an end portion flared gradually to a dimension transverse to the pin axis greater than the shank portion. The end portion is slotted to afford resilient resistance to entry and withdrawal into a hole. The pin head portion is disc-like, the shank portion is of uniform circular cross-section about the pin axis, and the shank merges gradually into the slotted end portion to define an hollow oval merging at the tip as a bight, the end portion thus being adapted for snapping into a suitable hole.The pin is especially adapted to use with a circuit element carrier having an inverted U-channel in which the element is carried. The element may be inserted into a pair of holes in the top and bottom wall of the inverted U-channel, so that the shank of the element serves as a stop to prevent longitudinal escape of an element beyond the pin shank. The pin may be withdrawn after insertion and reused in the same or other holes of the same or other like carriers.
